Update: Start time has been changed to 3PM

The IEEE Northern Canada Section Antennas & Propagation Society and the Microwave Theory & Techniques Society (IEEE NCS APS/MTTS) joint chapter is pleased to announce another Distinguished Lecturer seminar. Dr. G. V. Eleftheriades from the University of Toronto will be giving a presentation titled Invisibility and Electromagnetic-Wave Manipulation with Metamaterial Structures.

Abstract

In this seminar we will describe our recent efforts toward electromagnetic-wave manipulation using engineered structures (metamaterials) and related concepts. First, we will present some fundamental metamaterial concepts and structures related to imaging beyond the diffraction limit. This will be followed by our recent development of the “super-microscope”: An optical real-time microscope that overcomes the diffraction limit in the far zone without the need of any fluorescent labeling or fine scanning. Subsequently we will introduce the concept of the filed-discontinuity (FD) metasurface. We will then describe a thin active cloak which remains effective and thin regardless of the size and material composition of the object to hide. Finally, we will show applications of this FD-metasurface concept for manipulating electromagnetic waves at will including beam refraction and focusing.

Biography

George V. Eleftheriades earned his Ph.D. and M.S.E.E. degrees in Electrical Engineering from the University of Michigan, Ann Arbor, in 1993 and 1989 respectively. Currently he is a Professor in the Department of Electrical and Computer Engineering at the University of Toronto where he holds the Canada Research/Velma M. Rogers Graham Chair in Engineering. Eleftheriades introduced the concept of utilizing transmission lines to realize negative-index metamaterials in 2002. Together with his graduate students he has produced the first experimental demonstration of focusing beyond the diffraction limit with a Veselago-Pendry lens and invented a number of novel and practical antenna/microwave devices.  Eleftheriades is the recipient of the 2008 IEEE Kiyo Tomiyasu Technical Field Award. He is an IEEE Fellow and a  Fellow of the Royal Society of Canada. He has been the general chair of the 2010 IEEE Intl. Symposium on Antennas and Propagation and CNC/USNC/URSI Radio Science Meeting which was held in Toronto, Canada July 11-17, 2010.  Together with his graduate students he co-authored several award-winning papers including the 2010 IEEE Microwave and Wireless Components Best Paper Award, twice (2008 and 2012) the RWP King Best Paper Award from the IEEE Transactions on Antennas and Propagation, and the 2014 Piergiorgio Uslenghi Best Paper Award from the IEEE Antennas and Wireless Propagation Letters.
