Expansions for Two-Dimensional Back-Scattering from a Semi-Infinite Medium with Refractive Index Greater Than Unity
Two-dimensional scattering from a semi-infinite medium with a refractive index greater than unity is investigated. The incident radiation is collimated and normal to the surface of a pure scattering medium. The spatial variation of the incident radiation is characterized by a spatial frequency. Expansions valid for small spatial frequencies are developed and used to find solutions valid for large optical distances from an incident Gaussian-shaped laser beam. Expressions for the back-scattered intensity and flux are presented. Also, the solution for a strongly anisotropic phase function which is composed of a spike in the forward direction superimposed on an otherwise isotropic phase function is expressed in terms of the isotropic results. © 1991.
