N2 - In order to efficiently analyze planar photonic devices, we propose a discontinuous Galerkin time domain (DGTD) method with a generalized dispersive material (GDM) model. By integrating the GDM model into a full-wave DGTD formulation, we develop a general framework that includes a universal model for the analysis of arbitrary dispersive materials. As an example application, we utilize the new DGTD-GDM solver to analyze the response of a thin pixelized metasurface. The metasurface's optical responses are computed and compared to results obtained using CST, which provides validation of the efficiency improvement as well as accuracy of the proposed algorithm.
