A Hybridization of Multi-Level UV with the Hierarchical Fast Far Field Approximations for 3D Rough Surface Scattering

摘要：

　　This paper presents a hybrid multilevel UV method with the fast far field algorithm for the random rough surface scattering calculations.In the MLUV, a pro-ranked sampling algorithm is used to further compress the UV matrix pairs.To further improve the efficiency of the algorithm, from the second and third coarsest level, a hierarchical FAFFA is employed to further enhance the efficiency of the algorithm.A rough surface with 32-by-32 wavelengths is simulated with 1.5 million unknowns.The results show the efficiency of the algorithm.
