Backscattering of light from a layer of densely packed random medium
RÉSUMÉ
The theory of light scattering by systems of nonspherical particles is applied to derive equations corresponding to incoherent (diffuse) and interference parts of radiation reflected from the medium. A solution of the system of linear equations describing the light scattering by a system of particles is represented by iteration. The symmetry properties of the T-matrices and of the translation coefficients for the vector Helmholtz harmonics lead to the reciprocity relation for an arbitrary iteration. This relation is applied to consider the backscattering enhancement phenomenon. In the exact backscattering direction the relation between incoherent and interference parts is identical to that for sparse media.
