Speaker: Dr. Quevedo-Teruel at KTH Royal Institute of Technology

Oscar Quevedo-Teruel is a Senior Member of the IEEE. He received his Telecommunication Engineering Degree from Carlos III University of Madrid, Spain in 2005, part of which was done at Chalmers University of Technology in Gothenburg, Sweden. He obtained his Ph.D. from Carlos III University of Madrid in 2010 and was then invited as a postdoctoral researcher to the University of Delft (The Netherlands). From 2010-2011, Dr. Quevedo-Teruel joined the Department of Theoretical Physics of Condensed Matter at Universidad Autonoma de Madrid as a research fellow and went on to continue his postdoctoral research at Queen Mary University of London from 2011-2013.

In 2014, he joined the Division for Electromagnetic Engineering in the School of Electrical Engineering and Computer Science at KTH Royal Institute of Technology in Stockholm, Sweden where he is an Associate Professor and Director of the Master Programme in Electromagnetics Fusion and Space Engineering. He has been an Associate Editor of the IEEE Transactions on Antennas and Propagation since 2018 and is the founder and editor-in-chief of the EurAAP journal Reviews of Electromagnetics since 2020. He was the EurAAP delegate for Sweden, Norway, and Iceland from 2018-2020, and he has been a member of the EurAAP Board of Directors since January 2021. He is a distinguished lecturer of the IEEE Antennas and Propagation Society for the period of 2019-2022, and Chair of the IEEE APS Educational Initiatives Programme since 2020.

He has made scientific contributions to higher symmetries, transformation optics, lens antennas, metasurfaces, leaky wave antennas and high impedance surfaces. He is the co-author of 95 papers in international journals and 140 at international conferences.

Lens antennas are commonly englobed in a more general type of antennas, named aperture antennas. As their name indicates, they make use of a lens to modify the field distribution at the aperture of the antenna, which is typically fed by a single source. The lens is employed to transform the waves arriving from the source into a desired radiation pattern. Commonly, the desired radiation pattern is a directive beam in a given direction. However, similar to arrays, reflectors or leaky wave antennas, the goal changes depending on the application. For example, other desired features may be to produce multiple beams, or a broad beam-width.

Lenses were more commonly employed in optical applications. For this reason, most of the nomenclature comes from optics, and they are evaluated with rays theory. In this sense, the performance of the lens is conventionally described in terms of aberrations. An aberration is a failure of the rays to converge at the desired focus. This failure must be due to a defect or an improper design. Aberrations are classified as chromatic or monochromatic, depending on whether or not they have a frequency dependence. There are five monochromatic aberrations: spherical aberration, coma, astigmatism, Petzval field curvature, and distortion. However, this is not a common nomenclature for antenna designers in the radio-frequency and microwave regimes. In these regimes, the rays are substituted by electromagnetic fields, and the designers evaluate their antennas in terms of directivity, gain, efficiency, side lobe levels, cross polarization levels, etc. Therefore, there is a communication gap between both communities: optics and microwaves. In the THz regime, which is in between these two communities, researchers must understand both nomenclatures

In this talk, I will explain the operation of lens antennas, their potential, and two innovative techniques that have become very important in recent years. The first technique is transformation optics, which can be employed to produce three-dimensional directive lenses. The second one is metasurfaces, which can be used to produce low-cost and planar two-dimensional lenses. In the case of metasurfaces, fully metallic solutions are possible, which is a clear advantage in terms of losses. However, with the available technology, metasurfaces are only able to scan in one single plane. Finally, we introduce the concept of higher symmetries, that can be employed to enhance the bandwidth of conventional metasurfaces, or to increase their equivalent refractive indexes.

She has authored more than 20 papers published in refereed journals and conferences proceedings and also three patents during her Ph.D. and postdoctoral research. Dr. Alavi was a recipient of Mary Louise Imrie Graduate Student Award, honorable mention award in APS/URSI student paper competition (2019). Her research interests include antenna and propagation, passive and active microwave circuits, numerical methods in electromagnetics, inverse electromagnetic scattering, remote sensing, antenna over the air (OTA) measurements, and the application of machine learning and artificial intelligence in antenna measurement and fault detection of antennas and microwave circuits


Near-field to far-field transformation is a method for antenna characterization that computes the metrics defined in far-field by using mathematical transformation. This method makes it possible to have affordable very compact enclosures. Clearly, compared to direct and indirect far-field measurement methods, near-field to far-field transformation requires more near-field data correction and post-processing. This is because the distance between the probe and AUT is close, and also the collected data are used for further calculations. Therefore, any error in the collected data can propagate through all the calculations and decrease the accuracy. To correct the measured near-field data several correction methods are used as probe correction, phase center detection and correction, metallic parts and absorber effects removal. Furthermore, to reduce the measurement and post-processing time, instead of uniform sampling, an adaptive sampling technique is proposed and implemented. This method reduces the measurement and post-processing time to the quarter of the time of the uniform sampling. In this talk, I will present the algorithm and methods we have used for NFFF transformation, NF correction, uniform and adaptive NF data acquisition. We will have a live demo of our measurement setup, adaptive sampling method and Signal Shape software that we have developed for NFFF transformation.

Both the scientific and the defense communities wish to receive and process information occupying ever-wider portions of the electromagnetic spectrum. This can often create an analog-to-digital conversion “bottleneck”. Analog photonic channelization, linearization, and frequency conversion systems can be designed to alleviate this bottleneck. Moreover, the low loss and dispersion of optical fiber and integrated optical waveguides enable most of the components in a broadband sensing or communication system, including all of the analog-to-digital and digital processing hardware, to be situated many feet or even miles from the antennas or other sensors with almost no performance penalty. The anticipated presentation will highlight the advantages and other features of analog photonic systems (including some specific systems that the author has constructed and tested for the US Department of Defense), and will review and explain multiple techniques for optimizing their performance.

Adam Maunder: Metamaterial Liner for Magnetic Resonance Imaging

Adam Maunder completed a BSc Engineering Physics – Nanotechnology option in 2011 and a MSc degree Electrical Engineering – Biomedical in 2013 from the University of Alberta, Edmonton, Canada. From 2013-2015 he was a Research Assistant in the Mechanical Engineering Department at the University of Alberta. He completed his PhD degree at the University of Sheffield September 2019, where he researched RF hardware and imaging methods for fluorinated gas lung imaging. In August 2019 he joined the University of Alberta as a Postdoctoral researcher working in the Departments of Oncology and Electrical and Computer Engineering.

Abstract: There are a number of challenges to ultra-high field MRI (>4.7T): signal inhomogeneity, increased localized heating and challenging RF coil design with increased tuning complexity/instability. Travelling wave MRI, using the bore of the MRI scanner a waveguide, was developed as potential way to improve the homogeneity of MR signal excitation/reception and reduce the localized heating in the body. However, previous implementations have suffered from low efficiency and it requires a bore size sufficiently large to support propagating waves at the 1H Larmor frequency. A method of reducing the cut-off frequency for propagation with a thin metamaterial liner has been developed at the University of Alberta, permitting efficient MR excitation with the benefits of travelling wave MRI for reducing the cut-off frequency for propagation with a thin metamaterial liner has been developed at the University of Alberta, permitting efficient MR excitation with the benefits of travelling wave MRI for any field strength. This presentation introduces the framework developed to design metamaterial liners for below-cutoff propagation and the preliminary results of designs for whole-body 1H MRI and dual tuned 1H and 23Na head imaging at 4.7T.

Azita Goudarzi: Wideband High-Gain Resonant Cavity Antennas (RCA)

Azita Goudarzi received the B.S. degree in electrical engineering from the Shiraz University of Technology, and the M.S. degree in telecommunication, fields, and waves from the Shiraz University of Technology. She is currently pursuing the Master degree with the University of Alberta, Edmonton, AB, Canada. She has conducted researches on antennas. Currently working on the design of multi-beam antennas with high gain for the 5G communication systems. She is interested in designing reconfigurable metasurfaces, antennas with steerable or switchable beam, and CP high-gain antennas.

Abstract: Resonant cavity antennas (RCAs) are suitable candidates to achieve high-directivity with a low-cost and easy fabrication process. Since the PRS is a resonant structure, the bandwidth of RCA is narrow. Many investigations have been carried out to enhance the PRS bandwidth. Using a PRS with positive reflection phase gradient is a potential solution to increase the bandwidth of the RCAs. In this presentation, the study directions of the RCAs with the recent investigations and applicable examples are reviewed and followed by proposing a new wideband RCA with circular polarization. The proposed RCA uses a PRS structure whose reflection phase has a positive slope and a novel main radiator to illuminate the PRS layer.

Nabil Khalid: Battery-less RFID Based Wireless Sensors for 5G IoT

Nabil Khalid received the Bachelor of Electrical Engineering degree from Air University, Islamabad, Pakistan in 2013. His Majors involved Telecommunications, RF/Microwave, and RADARs. Following his undergrad he
worked at RWR Pvt. Ltd., Islamabad, Pakistan from 2013 to 2014 as a design engineer in the RF/Microwave department. His focus was on designing industrial-grade power amplifiers. From 2015 to 2017, Nabil worked at Next-generation and Wireless Communications Laboratory (NWCL) as a research assistant, and being a TUBITAK scholar, he received his Master of Science in Electrical and Computer Engineering from Koc University, Istanbul, Turkey. His focus was on developing the physical layer of THz Band wireless communications. Following that, he joined Intelligent Wireless Technologies Laboratory (IWT) in 2017 as a research assistant where his work, under the supervision of Prof. Pedram Mousavi, was focused on designing battery-less wireless sensors for 5G IoT applications. In 2020, as an Alberta Innovates Scholar, Nabil started pursuing his Ph.D. degree under the supervision of Prof. Ashwin Iyer at the Electrical and Computer Engineering Department, University of Alberta, Edmonton, Canada. He is focused on designing Battery-less wireless sensors.

Abstract: A novel zero-power wireless sensor architecture is proposed and demonstrated. The proposed wireless sensor, which is a passive sensor, combines UHF RFID and a capacitive sensor to enable the reading of physical and chemical parameters wirelessly, without compromising much on the read-range of conventional RFID tags. The sensor alters the phase of the backscattered RFID signal, which is detected at the receiver using a non-coherent IQ demodulator. Due to the universal nature of this architecture, any type of sensor, such as temperature, humidity, water level sensor, can be realized. 

Mahdi Bedani: Design of Over-the-Air Measurement Systems for Characterization of 5G Communication Devices

Mahdi Behdani received the B.S. degree in electrical engineering from the Ferdowsi University of Mashhad, in 2013, and the M.S. degree in telecommunication, fields, and waves from the Amirkabir University of Technology. He is currently pursuing the Ph.D. degree with the University of Alberta, Edmonton, AB, Canada. His current research interests include numerical methods in electromagnetics, electromagnetic scattering, antennas and propagation, and over-the-air measurement systems. He was a recipient of the Alberta Graduate Excellence Scholarship in 2020 and the CMC Industrial Collaboration Award in 2021.

Abstract: A portable near field (NF) measurement system is implemented in a mini anechoic chamber to debug and characterize the integrated devices deployed in the fifth generation (5G) communication technology. In this system, the NF data of the device under test (DUT) is acquired through novel methods and the obtained data is utilized to evaluate the performance of various wireless sub-systems such as micro-millimeter wave circuits and integrated antennas. The main advantage of the proposed setup over the conventional systems is its capability to characterize Integrated (Reconfigurable, Active, Phase Array …) Antennas where there is no access to the antenna to measure, separately. Since the integrated antennas are planed to be deployed in large scale in 5G technology, providing the telecommunication companies with such an economical measurement setup enables them to test their wireless products quickly and accurately, which is critical for those who are seeking opportunities in the 5G market.

Christopher Barker: Power-conserving field transformations using passive metasurfaces

Christopher Barker is a Ph.D. student in the Department of Electrical and Computer Engineering at the University of Alberta. He graduated from his undergraduate degree at the University of Alberta in Electrical Engineering in 2019 and is currently a graduate student under Professor Iyer. His research interests lie in the application of metasurfaces to curved surfaces in antenna radomes and waveguides.

Abstract: The ability of metasurfaces to manipulate waves over short distances make these devices attractive for applications ranging from microwaves to optics. These metasurfaces have a great ability to manipulate wavefronts making them desirable for applications such as antenna radomes and cloaking. However, these applications can be limited due to a requirement of local power conservation over the surface. This presentation will show how local power conservation effects the ability to achieve a desired field pattern and how recent works have been able to satisfy this constraint while still producing a desired field transformation.

Navid Hosseini: Selective Multivariable Analysis of Multicomponent Mixtures Using Harmonics of Planar EM Sensors

Christopher Barker: Power-conserving field transformations using passive metasurfaces

Navid Hosseini received the B.S. degree in electrical and computer engineering from University of Tabriz, Tabriz, Iran in 2009, and the M.S. degree from METU, Ankara, Turkey in 2012. From 2012 to 2016, he was with METU as research assistant working on MLFMA and genetic algorithm optimizations. He is currently a Ph.D. candidate in electrical and computer engineering department, University of Alberta, Edmonton, AB, Canada. He was a recipient of the FAI funds to work in Laboratori Nazionali del Gran Sasso (LNGS) INFN, Assergi, Italy 2010-2012. His current research interest includes RF CMOS integrated circuits, bio sensing, ADC, implementation of optimization algorithms for the post processing analysis.

Abstract: In recent years, selectivity have been a subject of many researches due to its practical challenges. The main issue is the limited number of output data which confines the degree of freedom for solving the more unknown of the problem.

The microwave resonators as the detecting devices can be useful for gathering the required information in the experiment. Their resonance shift is one of the features that is mostly utilized for sensing purposes. But for detection of multi-variable parameters, more than one independent feature is required. For overcoming this bottleneck, a new material characteristic is demanded for generating and defining the new independent features.

The rings are type of resonating structures that generate multiple harmonics in their frequency response. In order to make these elements changing independently, the variant permittivity profile of the materials under the test as a new parameter can be considered.

To present to a technical audience is challenging. To kindle curiosity and fire up your non-technical audience with your complex research—whether in person or online—is even more challenging, but developing such skills will be lifetime career assets.

The “virtual” medium, in particular, is fraught with technical and physical limitations, surprises, and, yes, wrong assumptions, easily leading you astray, e.g., from a professional posture. Then there is bandwidth, video resolution, microphone quality, your physical disconnect from your audience and slide(s), and more.

Our webinar contrasts “virtual” with in-person presentations, suggesting do’s and don’ts, with specific focus on the Microwave Week virtual Three Minute Thesis (3MT®) competition. We draw on experience: writing and directing plays, running entrepreneurial and exhibition booths, mentoring and coaching candidates for competitive presentations, as well as delivering relevant talks, webinars and workshops. We discuss storytelling, first impressions, citation, subtext, authenticity, articulation, script design, slide design, staging, stage presence, and respecting your audience.

We analyze 3MT® case studies from past IMS and Microwave Week 3MT® competitions, focusing on titles, slides, scripts, and opening and closing lines. While we expect students and young professionals to be our primary audience, professors and practicing engineers from industry should equally appreciate this webinar.

Meanwhile, check out our previous four related MTT-S webinars and watch videos from prior Microwave Week 3MT® competitions on the MTT-S IMS YouTube channel.
