Abstract :
F-BM/NSA, H.T. Chou et al., Radio Sci., vol.33, p.1277-87, with computational complexity of O(N) is very efficient in method of moment (MoM) modeling of large-scale scattering problems from rough surfaces. The previous formulation for PEC surfaces is extended to treat impedance surfaces. Similarly, numerical experiment shows F-BM/NSA is far more efficient than the competitive BMIA/CAG in the order of magnitude
