Wideband Active RISs: Architecture, Modeling, and Beamforming Design

Reconfigurable intelligent surfaces (RISs) have become a candidate for future 6G networks. The concept of active RISs has been recently proposed to overcome the multiplicative fading of RIS aided reflected links. However, due to the frequency-selective channels, the narrowband active RISs suffer fro...
