Self-Adaptive Differential Evolution-Based Inductance Optimization for Resonant Acoustic RIS in Underwater Communications

Underwater acoustic (UWA) communication systems suffer from limited bandwidth, severe multipath fading, and high propagation loss, which significantly constrain their achievable spectral efficiency and reliability. To improve UWA communication, reconfigurable intelligent surface (RIS) acts as a promising solution to en...
