Active Dual STAR-RISs for Full-Duplex MIMO Communications: An Energy-Efficient Optimization Framework

Simultaneously transmitting and reflecting reconfigurable intelligent surfaces (STAR-RISs) can dynamically adjust wireless channels through joint controls. The recent development of dual STAR-RISs (D-STAR) architecture provides capacity improvement by utilizing signals impinging from 360-degree for full-plane service c...

FSIM: Fluid Element Stacked Intelligent Metasurface for Mulituser Downlink Networks

Simulation results reveal that a compact FSIM with a small inter-layer thickness is preferable, as increasing the thickness weakens inter-layer coupling and degrades the achievable sum rate, and the proposed AO-based algorithm achieves superior rate performance compared to sub-schemes, metaheuristic methods, and conven...
