Report Title: Joint Modulations of Space-Time-Domain Signals in Electromagnetic Space

Abstract: 

Information metamaterials and metasurfaces provide a huge capability to manipulate the spatial beams, wave patterns, polarization states, and frequency spectra independently and simultaneously in real time on a single platform by controlling the digital coding pattern in space and coding sequence in time. This capability makes it possible to manipulate and modulate space-time-domain signals jointly in the electromagnetic space, which further establishes new-architecture radar systems by fusing the information metasurface as phase array for beam control and signal processor for information processing, and anti-radar systems to counteract the radar detection.

Biography: 

Tie Jun Cui is the Chief Professor of Southeast University, Nanjing, China, the Director of State Key Laboratory of Millimeter Waves, and the Founding Director of Institute of Electromagnetic Space, Southeast University. His research interests include computational electromagnetics and metamaterials. He proposed the concepts of digital coding and programmable metamaterials and established the new direction of information metamaterials, which can bridge the physical world and digital world, and are easy to integrate with the artificial intelligence. He published over 700+ peer-reviewed journal papers that have been cited by more than 86000 times (H-factor 140), and received many awards, including the National Natural Science Awards of China in 2014 and 2018, the Frontiers of Science Award in the First International Congress of Basic Science in 2023, the IEEE ComSoc Marconi Prize in 2024, the Tan Kah Kee Information Science Award in 2024, the Leading Technology (Natural Science) Award in 2024 World Internet Conference, and the ACES Technical Achievement Award in 2025. Dr. Cui is an Academician of Chinese Academy of Science and IEEE Fellow.
