Simulation of Circular Cylindrical Metasurfaces Using GSTC-MoM

Modeling of circular cylindrical metasurfaces using the 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 circular cylindrical metasurface. The GSTC-MoM is validated by two examples: (1) anisotropic and gyrotropic metasurface capable of two field transformations; and (2) nongyrotropic metasurface capable of transforming the field generated by an infinite electric line source at origin to the field generated by a displaced electric line source. The formulations presented here can be used as a platform for deriving GSTC-MoM for 3-D spherical and conformal metasurfaces.
