摘要
F-BM/NSA [3] 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 here extended to treat impedance surfaces. Similarly, numerical experiment shows F-BM/NSA is far more efficient than the competitive BMIA/CAG [4] in the order of magnitude.
