SYNOPSIS
Recently, a conformal surface plasmon (CSP) structure has been successfully proposed which is believed very promising for the design of plasmonic devices and circuits in the frequency range from microwave to mid-infrared. In this talk, I will present the investigation on both the symmetric and asymmetric CSP structures. By utilizing different guided modes, various waveguide devices such as the frequency splitter, directional coupler, or band-pass filter have been proposed in the microwave frequency range. The designed devices exhibit good performance that is validated through both electromagnetic simulation and the experimental test on fabricated prototypes. It is believed that such single-conductor CSP structure and related waveguide devices may be scaled down to other frequencies such as the millimeter wave, or even the terahertz range.  

ABOUT THE SPEAKER
Yijun Feng received the M.Sc. and Ph.D. degrees from the Department of Electronic Science and Engineering, Nanjing University, in 1989 and 1992, respectively. Since 1992, he has been a faculty member and is currently a full professor in the Department of Electronic Engineering at School of Electronic Science and Engineering, Nanjing University. From September 1995 to July 1996, he was a visiting scientist with the Physics Department, Technical University of Denmark. From August 2001 to August 2002, he was a visiting researcher with the University of California at Berkeley. Dr. Feng’s research interests include the electromagnetic metamaterial and application to microwave and photonic devices, electromagnetic wave theory, and novel microwave functional materials. He has conducted more than twenty scientific research projects including National 973, 863 Projects and the National Natural Science Foundation projects in China. He has received the 2010 Science and Technology Award (First grade) of Jiangsu Province, China, and the 1995 Scientific and Technological Progress Award by Minister of Education, China. He has authored or co-authored over 150 journal papers and over 120 referred international conference papers.
