Abstract :
We propose a comprehensive analysis for the evaluation of the scattering from randomly inhomogeneous semi-infinite media, including both interfacial roughness and volume inhomogeneities, by applying the methodological approach of the Volumetric Perturbative Reciprocal Theory (VPRT). An unifying perspective on the scattering phenomenon considered in its entirety is gained and an analytic scattering model is obtained.
