Modeling of dispersive media within the Discontinuous Galerkin Finite Element Time-Domain method

In this paper, a high-order DGFETD algorithm is proposed for simulating the fields in dispersive media based on an ADE formulation. The method is applied to a Drude and multiple pole Debye and Lorentz dispersive media models. The proposed algorithm is validated through the simulation of a number of canonical problems demonstrating that the algorithm preserves the high-order accuracy of the DGFETD method.
