Computational Electrodynamics - the FDTD method (2nd Edition) 3 Dimensional FDTD codes implemented by Matlab and include Dey-Mittra Mesh Generator. The Dey-Mittra Mesh Generator allows you to input a 2-d geometry to solve scattering problems. The geometry is input as straight line segments or circular arcs.
