Abstract:

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.

Abstract:

Microwave is not just for cooking, smart cars, or mobile phones. We can take advantage of the wide electromagnetic spectrum to do wonderful things that are more vital to our lives. For example, microwave ablation of cancer tumor is already in wide use, and microwave remote monitoring of vital signs is becoming more important as the population ages. This talk will focus on a biomedical use of microwave at the single-cell level. At low power, microwave can readily penetrate a cell membrane to interrogate what is inside a cell, without cooking it or otherwise hurting it. It is currently the fastest, most compact, and least costly way to tell whether a cell is alive or dead. On the other hand, at higher power but lower frequency, the electromagnetic signal can interact strongly with the cell membrane to drill temporary holes of nanometer size. The nanopores allow drugs to diffuse into the cell and, based on the reaction of the cell, individualized medicine can be developed and drug development can be sped up in general. Conversely, the nanopores allow strands of DNA molecules to be pulled out of the cell without killing it, which can speed up genetic engineering. Lastly, by changing both the power and frequency of the signal, we can have either positive or negative dielectrophoresis effects, which we have used to coerce a live cell to the examination table of Dr. Microwave, then usher it out after examination. These interesting uses of microwave and the resulted fundamental knowledge about biological cells will be explored in the talk.

Abstract:

In the next future we will be surrounded  in our daily lives by a multitude of small, relatively inexpensive computing devices, equipped with wireless communication and sensing featuring the concept of  “pervasive intelligence”, a basis from which we can envision our future world as an Internet of Everything (IoT/IoE), in terms of both a consumer IoT/IoE and the Industrial IoT. With this scenario in mind, one of the main challenging task is the wireless powering of a multitude of ubiquitous devices and machines to allow truly perpetual wireless-powered communication (WPC).

This webinar first describes possible solutions for the RF architectures of transmitting and receiving sides for battery-less scenarios, showing how multi-domain design techniques, combining EM theory and numerical simulation with nonlinear circuit design can provide reliable system implementaions; secondly the effective exploitation of such systems is shown through some significant applications, such as high precision localization (centimeter-level ) and tracking, adopting UWB communication, and predictive maintenance in machineries and industrial plants scenarios exploiting low-energy communications. The design challenges for both the transmitting and receiving subsystems are presented together with the performance achievements in real scenarios.

Abstract

Fig. 1: Transformation of a cylindrical wave into a plane wave by using a convex lens represented with rays and waves.

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.

Abstract:

Recent progress in semiconductor devices on compound semiconductor or silicon substrates has made it possible to produce more power and receive a signal with less noise at THz frequencies. Various integrated circuits for the THz radio front-end functional blocks, including power and low-noise amplifiers, modulators and demodulators, and oscillators, have been demonstrated in the last decade. In the first experimental demonstration conducted in 2004, bulky instruments originally developed for THz spectroscopy were used to transmit pulsed THz signals carrying a 7-kHz bandwidth audio signal across a short free space. However, recently, there have been several successful demonstrations of multi-Gbps data transmissions at THz frequencies with state-of-the art devices and components. In this talk, the first prototype of a THz wireless communications system designed under the ‘touch-and-go’ scenario will be presented. I clarify the concept of the KIOSK data downloading system, cover some considerations in this work, and present a brief link-budget plan. We will then overview technologies for implementing THz components operating at 300 GHz and their performance, followed by preliminary investigation of the channel responses and the experimental demonstration results. At the end of the presentation, we will discuss several issues that need to be addressed for the future of the THz communications systems, in terms of system architectures, packaging and potential applications.
