Conventional frequency selective surface (FSS) consists of a two-dimensional (2-D) periodic array of unit-cells, which are either printed on a dielectric layer or etched out of a conductive surface. These simple 2-D surfaces suffer from poor frequency selectivity and unstable response under different incident angles. Recently, an innovative concept of three-dimensional (3D) frequency selective structure was proposed to alleviate the disadvantages of traditional FSSs. The 3-D frequency selective structure is composed of a 2D periodic array of vertical microstrip lines, which is very promising for the realization of compact high-performance FSSs. This talk will introduce the proposed 3-D frequency selective structure. Mode-matching formulation for analyzing the structure will be briefly presented and numerical results are provided and validated by measured ones. Possible research topics for further investigation are also suggested at end of the talk.


Zhongxiang Shen received the B. Eng. degree from the University of Electronic Science and Technology of China, Chengdu, China, in 1987, the M. S. degree from Southeast University, Nanjing, China, in 1990, and the PhD 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 1999, he joined Nanyang Technological University, Singapore, where he is presently an Associate Professor in the School of Electrical and Electronic Engineering.


His research interests include design of small and planar antennas for various wireless communication systems, design of thin absorbing layers, hybrid numerical techniques for modeling RF/microwave components and antennas. He has authored or co-authored about 200 journal and conference papers.
