Abstract :
An efficient fast far-field approximation based algorithm for computing the electric fields propagating over irregular terrain in two dimensions is described. Symmetric successive over-relaxation, or forward-backward, is used to compute the surface current in an efficient manner. The results suggest that under the magnetic field integral equation formulation the backscattered field is negligible and strongly support the use of the forward scattering assumption.
