A Wideband STAR-RIS Employing Shared-Aperture Polarization Conversion and Diagonal Switching Topology for 6G Applications
Simultaneously transmitting and reflecting reconfigurable intelligent surfaces (STAR-RIS) enable programmable wave control on both sides of a surface, extending wireless coverage beyond single-sided operation. However, practical STAR-RIS demonstrations in literature have narrow bandwidths, because it is challenging to...
