学术报告会通知

题 目:  Design of Square-Waveguide Ortho-Mode Transducers

报告人 Prof. Zhongxiang Shen

时  间 20131223日(周一)10:00~11:30

地  点江宁开发区,秣周东路9号,无线谷A33412会议室

主  办 东南大学毫米波国家重点实验室

         IEEE AP-MTT-EMC Joint Nanjing Chapter

         江苏省电子学会天线与微波专委会

内容简介:

This talk begins with the definition of ortho-mode transducer (OMT) and a review of existing OMTs. After that, we present a new equivalent circuit model for square waveguide T-junction, which is a key component used in most OMTs. The new equivalent circuit is then used to synthesize square waveguide ortho-mode transducers. Finally, a number of OMTs based on square waveguide are provided to demonstrate the synthesis theory.

报告人简介:

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 Jan. 1999, he joined Nanyang Technological University, Singapore, as an assistant professor. He has been an associate professor in the School of Electrical and Electronic Engineering, NTU, since Jan. 2004. Dr. Shen served as Chair of the IEEE MTT/AP Singapore Chapter in 2009. He is currently the Chair of IEEE AP-S Chapter Activities Committee.

His research interests include design of small and planar antennas for various wireless communication systems, analysis and design of frequency-selective structures, hybrid numerical techniques for modeling RF/microwave components and antennas. He has authored or co-authored more than 126 journal papers (among them 67 were published in IEEE Journals) and presented more than 120 conference papers.
