Here are some papers, programs, and links that let you become more familiar with finite difference time domain (FDTD) solvers for Maxwell’s Equations.

A paper by D.W. Ward, and K.A. Nelson (”Finite-difference time-domain (FDTD) simulations of electromagnetic wave propagation using a spreadsheet,” Comput. Appl. Eng. Educ., 13: 213-221 (2005)) teaches you the idea of FDTD by building a simple [...]

In the white paper on EM simulator techniques mentioned in my previous post, the authors note:
Even more than for MoM- or FEM-based solvers, the popularity of FDTD-based solvers has been facilitated by recent advances in the speed and memory capacity of computer hardware. FDTD is an inherently parallel method and therefore lends itself very well [...]
