We are concerned with the numerical simulation of metasurfaces modeled by generalized sheet transition conditions (GSTCs). A hybridizable discontinuous Galerkin (HDG) method is pro-posed to treat field discontinuity on metasurface. briefly recall mathematical expressions surface susceptibility tensors and present formulations HDG method. The examples simulating monoanisotropic metasurface show that proposed can easily adapt discontinuities caused GSTCs. Additionally, we COMSOL results for same further validate efficacy
