Equivalent Circuit Modeling of a Lumped-element Loaded Metasurface under Arbitrary Incidence and Polarization
Athanasios Nousiou, Christos K. Liaskos, Nikolaos V. Kantartzis +1
In this work we develop a simple equivalent circuit model (ECM) that predicts the spectral response of a lumped-element loaded single patterned layer reflective metasurface. The pr…
