N2 - A new formulation of integral equations based on generalized sheet transition conditions (GSTCs) for metasurfaces is proposed in this paper. Equivalent electromagnetic surface currents are introduced into the integral equation (IE) method to simplify the computation. To incorporate GSTCs with the IE method, the equations of GSTCs are rewritten with the surface currents. The proposed IE-GSTC can be divided into two independent parts: general surface scattering equations and GSTC equations. The scattering equations are universal, so the equation system can be applied to arbitrary metasurface scattering problems through adaptation of the GSTC equations. Therefore, this new formulation of IE-GSTC establishes a general framework for the simulation of metasurfaces.
