Abstract:

The last decade has witnessed dramatic decrease in the price and size of microwave electronics along with the advent of the radio-on-a-chip (RoC), the software-defined radio (SDR), and the single-chip radars. This spurred unprecedented growth in applications such as imaging, sensing and detection. From automotive radar to medical diagnostics and concealed-weapon detection, microwave imaging and detection define the next wireless revolution. We will introduce the methods of microwave imaging, which allow to see inside optically opaque objects. We will start with a brief summary of the models used to describe the wave propagation inside the imaged object and how these models relate the objects electrical properties to the microwave measurements. We will then discuss how these properties can be deduced from the measured data and be presented in the form of 3D images. As an illustration, we will then briefly dive into the inner workings of one prominent imaging method, namely, microwave holography.

  

Bio:

Natalia K. Nikolova (IEEE S93M97SM05F11) received the Dipl. Eng. (Radioelectronics) degree from the Technical University of Varna, Bulgaria, in 1989, and the Ph.D. degree from the University of Electro-Communications, Tokyo, Japan, in 1997. From 1998 to 1999, she held a Postdoctoral Fellowship of the Natural Sciences and Engineering Research Council of Canada (NSERC) at two Canadian universities, Dalhousie University in Halifax and McMaster University in Hamilton. In 1999, she joined the Department of Electrical and Computer Engineering at McMaster University, where she is currently a Professor. Her research interests include inverse scattering, microwave imaging, as well as computer-aided analysis and design of high-frequency structures and antennas. Prof. Nikolova has authored more than 260 refereed manuscripts, 5 book chapters, and the book Introduction to Microwave Imaging published by Cambridge University Press in 2017. She has delivered over 40 invited lectures around the world on the subjects of microwave imaging and computer-aided electromagnetic analysis and design.

Prof. Nikolova is a Canada Research Chair in High-frequency Electromagnetics. She is a Fellow of the IEEE and a Fellow of the Canadian Academy of Engineering (CAE). She served as an IEEE Distinguished Microwave Lecturer from 2010 to 2013.
