摘要：
We study three-dimensional (3-D) electromagnetic wave scattering from a buried object under a two-dimensional (2-D) random rough surface. PMCHW is used to the dielectric random rough surface, while EFIE is introduced to the perfect electric conductor (PEC) surface. Based on Method Of Moments (MOM), the surface integral equations are first discretized into a matrix form using RWG basis function, then BICGSTAB is used to solve the matrix in iterative manner. Due to the high memory demand of MOM, the 3DMLUV method is implemented to save the storage space and accelerate the matrix-vector multiplication.
