2D-FDTD-UPML simulation of wave propagation on dispersive media

Abstract

As one of the major computational electromagnetic tools, the finite-difference time-domain (FDTD) method finds widespread use as a solver for a variety of electromagnetic problems. In this paper we are interested in the implementation of a two-dimensional time-domain numerical scheme for simulation of wave propagation, on dispersive and inhomogeneous media with conductive loss which are based on Debye model and incorporated into the FDTD scheme by using the auxiliary differential equation (ADE) technique. The uniaxial perfectly matched layer (UPML) is used as an absorbing boundary condition to simulate an open space.
