A symbolic procedure for deriving various finite difference approximations for the three-dimensional Poisson equation is described. Based on the software package Mathematica, we utilize for the formulation local solutions of the differential equation and obtain the standard second-order scheme (7-po

Three dimensional parallel implementation of the perfectly matched layer (PML) formulations are presented for truncating finite-difference time-domain (FDTD) Grids. The FDTD computational domain is divided into subdomains using one-dimensional topology and the interprocessor communication operations
