MTT-S Distinguished Lecture: Sensing, Tracking, and Secured Communication with Artificial Electromagnetic Materials

Atlanta’s IEEE AP/MTT joint-chapter is hosting a virtual MTT-S distinguished lecture event on July 20th (Mon.) from 7:00PM-8:30PM EST. We invited Dr. Chung-Tse Michael Wu to give a talk titled: “Sensing, Tracking, and Secured Communication with Artificial Electromagnetic Materials.” Talk abstract can be read below. Anyone interested is welcome to attend! This lecture is sponsored by IEEE MTT Society Distinguished Lecturer Program. ————————————————————————————————————————————————————- What is IEEE AP/MTT? In Atlanta, the local chapters for the IEEE Antennas and Propagation Society (AP-S) and Microwave Theory and Technique Society (MTT-S) are merged to form the joint AP/MTT chapter. We are composed of members at various stages of their careers, who work and do research in various electromagnetics disciplines, like antenna design, microwave circuits, RF systems analysis, etc. We welcome any students, young professionals, researchers, and senior engineers in Atlanta to join our joint-chapter and participate in our technical and service activities. ————————————————————————————————————————————————————– Abstract: 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 endfire with a true broadside beam. They also ensure excellent impedance matching throughout their operational range, using a straightforward feeding mechanism. The CRLH LWAs’ ability to map frequency to space means unknown target locations can simply 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.
