A Discontinuous Galerkin method to solve electromagnetic problems

In this paper, we present a discontinuous Galerkin (DG) method to solve the Maxwell equations in time domain. This method allows us to treat efficiently in terms of CPU-time and memory storage electromagnetic compatibility (EMC) problems, by a using high order spatial approximation and a local time-stepping strategy on unstructured meshes. To improve its capacity to solve EMC problems, some physical models have been added to the method. In particular, a composite material model is presented in this paper.
