Dr. Chung-Tse Michael Wu is an assistant professor in the Department of Electrical and Computer Engineering at Rutgers, The State University of New Jersey. His research interests include applied electromagnetics, antennas, passive/active microwave and millimeter-wave components, RF systems and metamaterials. He received his B.S. degree from National Taiwan University (NTU) in 2006. He then received his M.S. and Ph.D. degree in the Department of Electrical Engineering, University of California at Los Angeles (UCLA) in 2009 and 2014, respectively. From September 2008 to June 2014, he worked as a graduate student researcher at the Microwave Electronics Laboratory in UCLA. In 2009, He was a summer intern in Bell Labs, Alcatel-Lucent, Murray Hills, NJ. In 2012, he was a special-joint researcher at Japan Aerospace Exploration Agency (JAXA) in Kanagawa, Japan. From 2014 to 2017, he was an assistant professor in the ECE department, Wayne State University (WSU) in Detroit, Michigan. Dr. Wu was also a visiting assistant professor at National Chung Hsing University, Taichung, Taiwan, in summer 2017.

Dr. Wu was a recipient of the National Science Foundation (NSF) Faculty Early Career Development (CAREER) Award, the WSU College of Engineering Faculty Research Excellence Award in 2016, and the DARPA Young Faculty Award (YFA) in 2019.


报告内容摘要:

Metamaterials (MTMs) are artificial electromagnetic materials with novel effective medium properties that may not be available in nature. The concept of metamaterial structures has led to the design of many novel circuits exhibiting component enhancements. One type of metamaterial-based antenna structure is so-called composite right/left-handed transmission line (CRLH-TL) leaky-wave antennas (LWAs). This kind of antenna structure has been shown to offer significant advantages over conventional LWAs. For example, a balanced CRLH-TL LWA is able to achieve continuous backfire-to-endfire frequency-dependent beam scanning with a true broadside beam, good impedance matching over an entire operating band with a simple feeding structure. Utilizing the frequency-space mapping characteristics of CRLH LWAs, the locations of unknown targets can be determined by simply reading the spectral components of the reflected wave. This results in a real time detection scheme since the data acquiring speed is mostly depending on the frequency sweeping speed of signal source, which is typically on the order of milliseconds. Furthermore, the field-of-view of the sensor can be enlarged due to the wide scanning angle provided by CRLH LWAs. Leveraging this unique feature of MTM antennas, various applications including fast 2-D beamforming, real-time remote sensing with large field-of-view that can be used in vital sign detection or motion detection.
