Prof. Tiejun Cui
Southeast University, China
Tie Jun Cui is the Chief Professor of Southeast University, Nanjing, China. He proposed the concepts of digital coding and programmable metamaterials and realized their first prototypes, based on which he further proposed information metamaterials to bridge the physical world and digital world, and developed the new architecture information systems. Dr. Cui has published over 600 peer-review journal papers, which have been cited by more than 50000 times (H-Factor 113), and licensed over 100 patents. Dr. Cui received the Natural Science Award (first class) from the Ministry of Education, China, in 2011, the National Natural Science Awards of China (second class, twice), in 2014 and 2018, and the Highly Cited Researcher Awards from Web of Science (top 1%), in 2019-2021, respectively. His researches have been widely reported by Nature News, MIT Technology Review, Scientific American, Discover, New Scientists, etc.
Dr. Cui is the Academician of Chinese Academy of Science and IEEE Fellow. He served as Associate Editor of IEEE Transactions on Geoscience and Remote Sensing, and Guest Editors of Science China - Information Sciences, Science Bulletin, IEEE JETCAS, and Research. Currently he is the Chief Editor of Metamaterial Short Books in Cambridge University Press, the Editor of Materials Today Electronics, Associate Editor of Research, and the Editorial Board Members of eLight, PhotoniX, Advanced Optical Materials, Small Structure, and Advanced Photonics Research. He presented more than 100 Keynote and Plenary Talks in Academic Conferences, Symposiums, or Workshops.
Speech Title: RIS and Information Metasurfaces
Information metasurfaces are described by digital elements 0 and 1 with the opposite electromagnetic (EM) responses (e.g. anti-phases). By designing different coding states of the digital elements, the EM waves can be controlled in real time and in the desired way. The information metasurfaces set up a bridge between the physical world and digital world. Due to their powerful capabilities in controlling the wireless environment in real time and programmable way, the information metasurfaces are good platforms of reconfigurable intelligent surfaces (RIS) that have been popularly investigated in the community of wireless communications. Beyond functioning as RIS, the information metasurfaces can play more important roles in wireless communications, including the new architectures of transmitter systems, intelligent sensing, imaging and recognition, and programmable AI computing.
