Microwave and mmWave Near-Field Imaging: Applications, Methods, and Challenges - Natalia K. Nikolova

As part of our 2020-2021 seminar series, the University of Toronto Student Chapter of the IEEE Antennas and Propagation Society (AP-S) presents: Microwave and Millimeter-Wave Near-Field Imaging: Applications, Methods, and Challenges, presented by Natalia K. Nikolova from McMaster University, on Friday, March 19, 2021, 4-5 pm EDT. Abstract: In the last decade, we have witnessed dramatic decrease in the price and size of on-chip transceivers and radars along with their increased functionality. This has spurred unprecedented growth in imaging, sensing and detection applications, defining the current and future growth of wireless technology. We will introduce the methods of real-time microwave and millimeter-wave imaging, which allow to “see” inside optically opaque objects. The electromagnetic models of wave propagation that link the object’s electrical properties to the microwave measurements are briefly introduced with an emphasis on the approximations, which enable real-time image reconstruction. We will discuss the detrimental effects of these approximations on the reconstructed images and how these effects are mitigated through the careful design of the acquisition apparatus and through data processing. We will briefly dive into the inner workings of two reconstruction methods, microwave holography and the scattered-power mapping, along with examples of real-time quantitative image reconstruction of complex dielectric objects.
