  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.
