Equivalence theorem for the spectral density of light waves scattered from different types of anisotropic media

Abstract

The spectral density equivalence theorem of light waves on scattering from different types of anisotropic media is discussed. The possibility of producing identical spectral density distribution as light waves are scattered by different anisotropic media is also discussed. Moreover, the conditions under which a determinate anisotropic medium and random anisotropic medium may produce identical spectral densities are obtained. It is shown that the complete equivalence theorem in whole space or the partial equivalence theorem in some special planes can be realized under particular conditions.
