Peculiarities of the angular power spectrum of scattered radiation by a random inhomogeneous dielectric slab

Statistical characteristics of the angular power spectrum of multiple scattered electromagnetic waves passing through randomly absorptive inhomogeneous plane layer with dielectric permittivity fluctuations are investigated. The point source and the detector are located on the opposite sides of the layer in homogeneous media with different dielectric permittivity and at terminal distances from the layer boundaries. Broadening of the angular spectrum and displacement of its maximum are obtained in the ray-(optics) approximation.
