Spectro-Temporal Dispersion-Engineered Electromagnetic Metamaterials for Sensing and Communication
IEEE North Jersey Section AP/MTT Jt. Chapter Co-Sponsors the TALK: "ISpectro-Temporal Dispersion-Engineered Electromagnetic Metamaterials for Sensing and Communication"
Metamaterials (MTMs) are synthetic electromagnetic materials possessing unique properties not found in natural materials. Their introduction has spurred the creation of innovative circuits with enhanced components. One notable metamaterial-based design is the composite right/left-handed transmission line (CRLH-TL) leaky-wave antennas (LWAs). These antennas offer continuous frequency-dependent beam scanning from backfire to end-fire with an accurate broadside beam. Using a straightforward feeding mechanism, they also ensure excellent impedance matching throughout their operational range. The CRLH LWAs' ability to map frequency to space means unknown target locations can be pinpointed by analyzing the spectral components of the returning wave. This paves the way for real-time detection, with data acquisition speeds mainly determined by the signal source's frequency sweep rate. The sensor's field of view is also expanded thanks to the wide scanning angle of CRLH LWAs. Such features enable applications like swift 2-D beamforming, expansive real-time remote sensing, vital sign monitoring, motion detection, and microwave imaging. Additionally, applying spatiotemporal modulation to CRLH LWAs can generate harmonic waves and enhance physical layer security, promoting safer wireless communication.

Biography:
Dr. Chung-Tse Michael Wu's research interests span applied electromagnetics, antennas, passive and active microwave and millimeter-wave components, MMIC, RF systems, and metamaterials. He earned his B.S. degree from National Taiwan University (NTU) in 2006, followed by his M.S. and Ph.D. degrees from the Department of Electrical Engineering at the University of California, Los Angeles (UCLA) in 2009 and 2014, respectively. From 2014 to 2017, he was an Assistant Professor in the ECE department at Wayne State University (WSU) in Detroit, Michigan. In 2017, he joined Rutgers University as an Assistant Professor and was promoted to tenured Associate Professor in 2022. Since 2024, he has been an Associate Professor with NTU.
Dr. Wu is a member of the Technical Committee for IEEE MTT-28 and MTT-4. He has received several prestigious awards, including the National Science Foundation (NSF) Faculty Early Career Development (CAREER) Award, the WSU College of Engineering Faculty Research Excellence Award in 2016, the Defense Advanced Research Projects Agency (DARPA) Young Faculty Award (YFA) in 2019, and the DARPA Director’s Fellowship Award in 2021. In 2022, Rutgers University honored him with the Board of Trustees Research Fellowship for Scholarly Excellence. He is the Vice Chair for the joint AP/ED/MTT chapter of the IEEE Princeton Central Jersey Section. He serves as an Associate Editor for IEEE Microwave and Wireless Components Letters, the IEEE Journal of Electromagnetics, RF, and Microwaves in Medicine and Biology, and IEEE Access.
