CPML Implementation for FCC-FDTD Method

Abstract

The convolutional perfectly matched layer is implemented for the face-centered cubic grid which can substitute the standard Cartesian (Yee) grid. The face-centered cubic grid proves to have better grid isotropy and relaxed stability criterion. Here, we implemented the convolutional perfectly matched layer as an absorbing boundary for the face-centered cubic computational domain. The efficiency of the convolutional perfectly matched layer is demonstrated by comparing the reflection error obtained in face centered cubic grid with the reflection error in the Yee's grid.
