T-Parameters Based Modeling for Stacked Intelligent Metasurfaces: Tractable and Physically Consistent Model
Hamad Yahya, Matteo Nerini, Bruno Clerckx +1
This work develops a physically consistent model for stacked intelligent metasurfaces (SIM) using multiport network theory and transfer scattering parameters (T-parameters). Unlike…
