Simultaneously Transmitting and Reflecting Reconfigurable Intelligent Surface–Aided Orthogonal Time Frequency Space System for 6G and Beyond High-Mobility Wireless Networks
Unlike conventional reflection-only reconfigurable intelligent surfaces (RISs), simultaneously transmitting and reflecting RISs (STAR-RISs) constitute a paradigm shift in intelligent surface design by facilitating electromagnetic wave manipulation in both transmission and reflection domains, thereby achieving full-spac...
