Transmission and Reflection Properties of a Random Medium

ABSTRACT The parabolic approximation for wave propagation in a random medium is extended to include the backscattering. Approximate analytic solutions for the mutual coherence functions of the transmitted and reflected waves due to a plane wave normally incident to a layer of random medium are obtained. The results are expressed in the form of a scattering matrix, which may be conveniently used in multi-layer problems. Some typical numerical results illustrating the effects of layer thickness and strength of permittivity fluctuation on the mutual coherence functions are presented.

Acoustic propagation in random layered media

We study how the presence of small scale random layering may affect the interpretation of acoustic scattering data. Our methods include theoretical analysis based on the idea of localization of states, in conjunction with Monte Carlo simulations of particular layered systems suggested by interesting geophysical examples. We show that the random layering can produce dramatic effects by leading to a cutoff frequency for transmission through the system.
