A Lorentzian Dispersion Model for Stacked Intelligent Metasurfaces

Stacked intelligent metasurfaces (SIM) provide a low-power means for MIMO transmission and reception using large multi-layer apertures that are digitally controlled. In this letter, we develop a SIM model that is consistent with metasurface theory. We use the Lorentzian function to emulate the amplitude-phase trade-off...
