Abstract

Wave scattering from a two-dimensional lossy dielectric random rough surfaces (three-dimensional scattering problem) with large permittivity is studied by using numerical simulations. A physics-based two-grid method (PBTG) is extended from 1D surfaces to 2D surfaces to deal with the problem. The sparse matrix canonical grid method (SMCG) is used in conjunction with the PBTG to speed up computation. Applying this method, the emissivities of random dielectric rough surfaces are calculated. The results are compared with those from the second order small perturbation method.
