Implementation of FDM in solving EM field problem over exact solution and accuracy analysis

This paper is a discussion on the implementation of finite difference method (FDM) in solving electromagnetic (EM) field problem. The iterative method and successive over relaxation (SOR) method is discussed and implemented as a technique of FDM. Here the exact solution, using separation of variables is also discussed and implemented. And finally, a comparison of accuracy is shown and discussed among these methods.
