Mutual Coupling and Unit Cell Aware Optimization for Reconfigurable Intelligent Surfaces

We introduce algorithms for optimizing a single-input single-output reconfigurable intelligent surface (RIS) assisted system. The RIS is modeled by using an electromagnetic-compliant framework based on mutual impedances and its reconfigurability is realized through tunable lumped impedances. In the...
