Abstract

The iterative forward-backward (FB) method is an efficient technique for numerical evaluation of scattering from perfectly conducting 1D rough surfaces. The method has been recently generalised to analyse scattering from dielectric 1D rough surfaces. In this paper the FB method for dielectric surfaces is framed within the theory of iterative methods for the solution of linear systems. In addition, application of the FB method to dielectric band-limited fractional Brownian motion (fBm) fractal surfaces is addressed.
