RIS Optimization and Scaling Laws in Multi-Operator Systems: Is Quadratic Scaling Achievable?
Quadratic scaling of received signal power with RIS element count is achievable in L-operator systems only when group-connected BD-RIS has group size Gs >= L; conventional single-connected RIS yields only linear scaling.
