Multi-user frequency selective beam steering by reconfigurable intelligent surfaces in the Ka-band

Multi-user frequency selective beam steering by reconfigurable intelligent surfaces in the Ka-band

Abstract Reconfigurable intelligent surfaces (RIS) have been proposed to extend the coverage of wireless communication signals at mm-wave frequencies. Here, we designed and fabricated a reconfigurable intelligent surface (RIS) for multi-user frequency selective beam steering (MU-FSBS) that achieves...
