Abstract

The order-of-scattering solutions (Bellman, Vasudevan, and Ueno (BVU) series) of the Riccati equation for the reflection function of an inhomogeneous slab are used to calculate the mean power intensity for a medium having random fluctuations of its dielectric constant. A solution for a Fokker-Planck-like differential equation for the joint probability density of the real and imaginary parts of the reflection function is obtained using a technique due to Van Kampen for nonlinear equations with multiplicative noise. The mean reflected power calculated from the probability density function is in agreement with that derived from the BVU solutions.
