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.
