Simulation of Circular Cylindrical Metasurfaces using GSTC-MoM

Abstract

A modeling of circular cylindrical metasurfaces using Method of Moments (MoM) based on Generalized Sheet Transition Conditions (GSTCs) is presented. GSTCs are used to link the integral equations for fields on the inner and outer contour of the cylindrical metasurface. The GSTC-MoM is validated by a case of an anisotropic, gyrotropic metasurface capable of two field transformations. The formulations presented here can be used as a platform for deriving GSTC-MoM for 3D spherical and conformal metasurfaces.
