This edition demonstrates how to pose, numerically analyze, and solve electromagnetic problems (EM). Significant updates include the transition of all FORTRAN code into the more widely used MATLAB® format as well as improvements made to the standard algorithm for the finite difference time domain (FDTD) method and the treatment of absorbing boundary conditions in FDTD, the finite element method, and the transmission-line-matrix method. In addition to updated examples and new homework problems throughout, the second edition adds a chapter on the method of lines. An appendix covers use of MATLAB code.
