Abstract

We propose a discontinuous Galerkin time domain (DGTD) method based on the generalized sheet transition conditions (GSTCs) to analyze arbitrarily curved metasurfaces. The discontinuities in the electromagnetic field near the metasurface are simulated by placing virtual edges on both sides of the metasurface. The GSTC approach is incorporated in the update equations in standard DGTD algorithm. Furthermore, we have extended the method to arbitrarily curved metasurfaces, which has been proposed and verified for the first time. This is also the first time that the DGTD scheme is extended to include the GSTCs for metasurfaces. Two examples are simulated to validate the proposed method.
