This paper investigates a reconfigurable intelligent surface (RIS)-aided hybrid beamforming (HBF) framework for downlink multi-user millimeter-wave systems operating under practical hardware constraints, and develops a hardware-constrained optimization problem to maximize the geometric mean (GM) of user rates, thereby...

In this paper, we investigate the sum rate maximization problem for integrated sensing and communication (ISAC) systems enabled by a flexible intelligent metasurface (FIM) deployed at the base station. By enabling element movement through surface morphing, the FIM introduces additional spatial degrees of freedom that c...
