Abstract

The far-zone scattered field generated by an anisotropic particulate medium with electromagnetic plane incident waves is discussed. The analytical expressions of the spectral density and spectral degree of coherence of the scattered field are derived, which show that the coherence properties of the scattered field depend on the characteristics of each particle and the distribution of particles. By simulations of two special cases, i.e., anisotropic random particles with isotropic determinate distribution and isotropic determinate particles with anisotropic random distribution, the properties of the medium and the polarization states of the incident wave play roles in the distribution of the spectral degree of coherence of the scattered field. Moreover, the general condition, anisotropic particles with anisotropic distribution, is briefly discussed. By comparing the results generated by different parameters, the coherence changes of scattered field are found in the scattered field.
