Student Seminar Series – Session #3
We are pleased to announce the third and final session in our student seminar series. Two seminars will be given on on Wednesday, March 23 from 3:00 pm – 4:00 pm in NREF 1-003.
Seminar #1: Dennis Ramsawak, Bertie Chen, and Michael Amyotte – Undergraduate Capstone Project
Biography
Dennis, Bertie and Michael are all currently perusing their degrees in Electrical Engineering at the University of Alberta. In their 4th year they all decided to embark on a capstone project related to the design, fabricating and testing of Microwave Sensors for Oil and Gas applications. Their work in the development of the sensor has sparked an interest in this respective discipline and they are all intending to further pursue the development of sensing devices.
Seminar #2: Mohammad Zarifi – “Microwave Planar Resonator Sensors for Nano-scale Phenomena Detection“
Abstract
Microwave planar resonators are emerging as cheap, compact, label-free and highly sensitive detection and quantification devices. These devices are particularly favored for sensing purpose due to their geometry, electromagnetic field enhancements in the coupling gap and compatibility with established printed circuit board manufacturing. However, the lack of selectivity and resolution in what is essentially a permittivity-sensing method are impediments to wider adoption and implementation of this sensing platform. This work is presenting selectivity and sensitivity engineered microwave sensor by employing Micro and Nano-scale materials. UV-sensitive titanium dioxide nanotubes are used to enhance the sensitivity and selectivity in our approach, which demonstrate promising results in gas sensing and light-intensity detection applications.
Biography
Mohammad Hossein Zarifi, is currently a postdoctoral fellow at the University of Alberta, Canada. His research focus includes design of high-speed and low-power analog circuits, analog-to-digital converters for biomedical and communication applications and microwave planar structures for sensing application. Dr. Zarifi received CMC-NRC first place award, on industrial collaboration, for the innovative microwave sensors, in 2015, Canada. He is the author of 27 peer-reviewed journal publications, and 19 conference papers or abstracts. His current research is investigating the new emerging technologies for the state of the art sensors, with focus on microwave resonators.
