Introduction to numerical techniques in electromagnetics
In the earlier chapters, we considered the analytical techniques for solving electromagnetic field problems and obtained solution in the close form. In obtaining such closed form solution we are often required to make certain assumptions so that analysis is simplified. However, while solving practical problems when analytical solutions become extremely complex or intractable, we resort to non analytical methods. With the advent of fast digital computers, numerical methods for solving EM field problems have become very popular. These are many numerical techniques which have been developed over the last few decades. In this section we shall briefly discuss two popular methods for solving EM field problems.
