Mitigating performance degradation of RIS due to element failures using a genetic algorithm-based sparse array strategy

A Genetic Algorithm (GA)-based sparse array strategy is introduced to mitigate the performance degradation of Reconfigurable Intelligent Surfaces (RIS) in satellite communication systems due to reconfigurable element failures in this paper. Such failures hinder real-time adjustment via Field Program...
