Title: Amplifying information meta-surfaces for wireless transfers of information and power

Abstract: Space-time-coding information metasurfaces have great capabilities in controlling the phases, amplitudes, frequency spectra, polarization, waveforms, and spatial beams of electromagnetic (EM) waves, and modulating digital information in the EM space. Integrating amplifiers into metasurface units, a new function of wireless power transfers is added to the amplifying information metasurfaces. In this talk, I will introduce the principles and techniques to use the amplifying information metasurfaces for wireless communication and wireless power transfer independently and simultaneously.

Bio: Tie Jun Cui is a Chief Professor of Southeast University, Nanjing, China, Director of State Key Laboratory of Millimeter Waves, and Founding Director of Institute of Electromagnetic Space, Southeast University. 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 81000 times (H-factor 137), 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.
