The solution of Maxwell's equations for E&M Waves using the finite difference time domain method.
This is just one of 61 Lectures covering a full one-year Course in Computational Physics previously taught by Rubin Landau at Oregon State University. (The number refers to the chapter and section in reference 1 below.)
There are video modules (Flash), slides, codes, quizzes, and all the lectures at:
