Abstract

Unconditionally stable complex envelope perfectly matched layer formulations are presented for truncating dispersive finite difference time domain grids. The method is based on the alternating direction implicit scheme and can be used for modeling electromagnetic applications with band limited sources. Numerical examples carried out in 2-D linear Lorentz dispersive media are included to show the validity of the proposed formulations
