Abstract

The exact formulation for radiative transfer in an absorbing and isotropically scattering two-layer slab with Fresnel interfaces is developed. The resulting integral equations are solved by the Nyström method. The present model allows refractive indices larger than one; directional interface reflectivities and multiple specular reflections are taken into account. The hemispherical reflectivity and transmissivity of the slab are determined. The present results are compared with the transparent-interface results and the single-layer results reported in the literature. Excellent agreement is found, and so the present solution procedure is valid. The effects of scattering albedos, optical thicknesses and refractive indices of the two layers on the hemispherical reflectivity and transmissivity are investigated.
