The forward–backward method with a novel spectral acceleration algorithm (FB/NSA) for the computation of scattering from two‐dimensional large‐scale impedance random rough surfaces

The forward–backward method with a novel spectral acceleration algorithm (FB/NSA) has been shown to be a very efficient (Ntot) iterative method of moments, where Ntot is the total number of unknowns to be solved, for the computation of electromagnetic wave scattering from two-dimensional (2-D) perfectly conducting rough surfaces. In this paper, the method is extended to treat impedance rough surfaces. It is found that the 2-D NSA algorithm for the impedance case is similar to the one for the perfectly conducting case. Comparisons of numerical results between the standard 2-D FB and 2-D FB/NSA methods show that the latter yields very accurate results with an appreciable reduction of CPU time. © 2001 John Wiley & Sons, Inc.
