Abstract
A model of anisotropic quasi-homogeneous media with adjustable boundaries is presented with the help of the three-dimensional multi-Gaussian function. After that, the behaviors of the far-zone field of light waves on scattering from an anisotropic semisoft-boundary quasi-homogeneous medium are illustrated. It is shown that the spectral density of the scattered field is flattened-Gaussian-centered, owing to the semisoft boundary of the scatterer, while the spectral degree of coherence is Gaussian-centered, which is independent of the boundary of scatterer. It is also shown that both the spectral density and the spectral degree of coherence are anisotropic because of the anisotropy of the scattering medium.
