Scattering from Large-Scale Stratified Rough Surfaces using Improved BMIA/CAG

Abstract

A numerical method is presented to analyze the scattering behavior of large-scale stratified rough surfaces. The method improves the banded matrix iterative approach / canonical grid (BMIA/CAG) by adopting some simple formulas to calculate the coupling interactions between different surfaces. Such treatment reduces the complexity of the method at expense of little accuracy when the roughness of surfaces can be ignored compared to the distance between surfaces, and also reduces the computation time by parallel implementation technique. Based on emissivity calculation, the one-dimensional method is proven to be effective for the analysis of some scattering properties. Then the proposed method is compared with the method of moments (MoM) by example of multilayered lunar regolith. Details of numerical results are given and discussed, which provide a guide in the application of the improved method.
