Abstract

In this letter, we present a method to efficiently hybridize the discontinuous Galerkin time domain method (DGTD) with the classical finite difference time domain method (FDTD). The main advantage of this hybrid method is that it maintains the generality of FDTD to treat the main part of a complex inhomogeneous problem, applying only DGTD for accurately taking into account the geometrical details of the objects which would not be properly treated with the usual staircased approximation of the classical FDTD.
