A Framework for Stacked Intelligent Metasurfaces With Geometry Design for Near-Field Communications

Stacked intelligent metasurfaces (SIMs) enable near-field wavefront shaping via multiple programmable layers. However, widely used wave-domain models often neglect power scaling, mutual coupling, and geometric flexibility, while multiport-network formulations are physically consistent but computationally heavy and typi...
