Optimization of CFS-PML Parameters for FD-ADI-FDTD

Abstract

The frequency dependent alternating direction-implicit finite difference time domain (FD-ADI-FDTD) method is designed to handle FD materials and there is to date no study of the influence of FD materials on the complex frequency-shifted perfectly matched layer (CFS-PML) parameters. This paper studies the effects of the CFS-PML parameters on the reflection coefficient with regard to the FD media parameters
