Point-to-point wave propagation through an intermediate layer of random anisotropic irregularities: Phase and amplitude correlation functions

The problem of wave propagation from a point source to a point of observation through an intermediate slab containing random weak dielectric irregularities is considered. Under the assumption that the spatial correlation of the permittivity is a Gaussian one with correlation distances much larger than the wavelength, the phase and amplitude auto- and cross-correlations are computed for any distance of source and receiver to the slab. Comparison is made to the analyses by Karavainikov and Yeh which are shown to be limiting cases of the present work.
