摘要
A novel bi-iterative model is proposed to solve the extra large-scale composite electromagnetic (EM) scattering from an object above a rough surface. For the rough surface scattering, the forward-backward methodology and its modification with under-relaxation iteration method are developed to accelerate the convergence of the iterative physical optics (IPO) and improve its robustness. Meanwhile, the local iteration methodology and the fast far field approximation (FaFFA) in the matrix-vector product are proposed to reduce effectively the computational complexity and further improve the efficiency of the whole iteration process. Hence, this model can greatly reduce the computational costs, including both RAM memory and CPU time.
