Optical Cross Sections of a Random Layer, introducing an appropriate boundary condition for the diffusion equation. This enables us to obtain specific expressions of the cross sections in terms of a simple boundary-value solution of the diffusion equation. Finally, the boundary conditions are generalized to the case in which media are random on both sides of a rough boundary.享乐主义者 发表于 2025-3-24 04:37:25

Operator Representation of a Random Medium,, say .., and the situation is also the same for a wave in the random medium, which is a functional of the random medium .(x̂), say .[.]. The problem is therefore basically reduced to finding the characteristic functional of the wave for a given ... We begin this subject by learning how the statistiGerontology 发表于 2025-3-24 13:33:25
Waves in a Homogeneously Random Medium,riously affected by every fluctuation of the medium, locally, in contrast to the case of turbulent air, in which the wave is negligibly affected by the medium fluctuation for the propagation over a distance of the order of the medium correlation distance.沙草纸 发表于 2025-3-24 17:26:32

Forward Scattering Approximation,medium can be assumed to be subject to Gaussian statistics in most cases, fulfilling the condition described in Sect. 1.3. Also, the forward scattering approximation is possible in the case of light wave propagation through air where the wave is scattered mostly in the forward direction. This enable
