Circuit Modeling of Metascreen using Generalized Sheet Transition Conditions and Babinet’s Principle

A method for modeling surface admittance of metascreen from generalized sheet transition conditions (GSTCs) and Babinet’s principle is presented. The surface impedance and admittance of a metascreen can be calculated from the surface impedance and admittance, which are converted from the surface susceptibilities of the metafilm. The proposed method is applied to partially reflective surfaces (PRS) and verified by comparison with full-wave simulation results.
