Realization of Reconfigurable Intelligent Surfaces With Space–Time-Coded Metasurfaces

IEEE Transactions on Antennas and Propagation
This paper presents experimental realization of a reconfigurable intelligent surface (RIS) using space-time coding metasurfaces to enable concurrent beam steering and data modulation. The proposed approach harnesses the capabilities of metasurfaces, allowing precise temporal control over individual unit cells of the RIS.
