Study of a remote probing technique for inhomogeneous media

Abstract
Most available methods for remote probing of inhomogeneous media make use of the knowledge of the reflection coefficient of the medium as a function of the frequency of the probing plane wave. In this letter, the inversion problem is examined via an alternative approach in which the incident angle of the plane wave is varied instead of the frequency. An analytical method is developed for processing these reflection coefficient data. A critical evaluation of the numerical aspects of the method is included.
