characteristics of Gaussian beam scattering from the target, which is the statistical average and mutual correlation function of the statistical characteristics. Under the laser beam incidence, numerical method is used to calculate the correlation function of a sphere are change with scattering angles in different radii, material, incident condition, and so on. The mutual correlation functions of metal materials are larger than that of non-metallic materials. There have a stronger backward-scattering of metal sphere and a stronger forward-scattering of non-metallic sphere. Roughness of material surface and dimension of sphere have bigger influences on the correlation functions of scattering fields. And mutual correlation functions have same distribution in different polarization. Our works will be further be based on studying other high order statistical moments of laser beam scattering from target with rough surface.
Expressions of two wave vectors in anisotropic medium are firstly developed. The size and direction of the reflection wave number and the transmission wave number related to the two wave vectors are researched respectively as well as the relationship of size between the two transmission waves. The reflection coefficient and the transmission coefficient of the interface between the isotropic medium and the anisotropic medium are then derived. Finally the numerical simulations of the obtained results are presented and the effectiveness of the results is tested.
