Absorptive Frequency-Selective Structures

IEEE AP-S DL Talk sponsored by North Jersey Section

In this talk, the speaker will introduce the concept of absorptive frequency-selective structures, which are different from the traditional frequency-selective structures (FSS). By introducing losses or absorbers into the traditional FSS, designers can design both absorptive frequency-selective reflection (AFSR) and absorptive frequency-selective transmission (AFST) structures. The lecture will focus on first introducing the motivation behind the design of AFSR and AFST structures.

Topic:

Absorptive Frequency-Selective Structures

In this talk, the speaker will introduce the concept of absorptive frequency-selective structures, which are different from the traditional frequency-selective structures (FSS). By introducing losses or absorbers into the traditional FSS, designers can design both absorptive frequency-selective reflection (AFSR) and absorptive frequency-selective transmission (AFST) structures. The lecture will focus on first introducing the motivation behind the design of AFSR and AFST structures. A brief review of the state-of-the-art designs of AFSR and AFST structures will then be given. Design considerations will be presented to widen the absorption bandwidth and reduce the reflection or transmission loss for the frequency band of interest. Practical examples will be finally provided to demonstrate the performance of the designed AFSR and AFST structures with simulation and measurement results. Further research topics related to absorptive FSS will also be suggested in the end.

Biography:

Prof. Zhongxiang Shen received a B. Eng. degree from the University of Electronic Science and Technology of China, Chengdu, China, in 1987, an M. S. degree from Southeast University, Nanjing, China, in 1990, and a Ph.D. degree from the University of Waterloo, Waterloo, Ontario, Canada, in 1997, all in electrical engineering. From 1990 to 1994, he was with Nanjing University of Aeronautics and Astronautics, China. He
was with Com Dev Ltd., Cambridge, Canada, as an Advanced Member of Technical Staff in 1997. He spent six months each in 1998, first with the Gordon McKay Laboratory, Harvard University, Cambridge, MA, and then with the Radiation Laboratory, the University of Michigan, Ann Arbor, MI, as a Postdoctoral Fellow. In Jan. 1999, he joined Nanyang Technological University, Singapore, as an assistant professor, where he is currently a full professor in the School of Electrical and Electronic Engineering. Dr. Shen served as the Chair of the IEEE MTT/AP Singapore Chapter in 2009. From Jan. 2010 to Aug. 2014, he was the Chair of IEEE AP-S Chapter Activities Committee. From July 2014 to December 2018, he served as the Secretary of IEEE AP-S. He was an elected AdCom member of the IEEE AP-S from Jan. 2017 to Dec. 2019. He is currently serving as an Associate Editor of the IEEE Transactions on Antennas and Propagation. Prof. Shen is an IEEE Fellow. His research interests include small and planar antennas for various wireless communication systems, analysis, and design of frequency-selective structures and absorbers, and hybrid numerical techniques for modeling RF/microwave components and antennas. He has authored more than 200 journal papers (among them 140 were published in IEEE Journals) and also presented more than 180 conference papers.
