Two-dimensional isotropic scattering

AbstractAn exact formulation for the source function, the radiative flux, and the intensity is presented for a two-dimensional, finite, planar, isotropically scattering medium. Exact expressions are obtained for both collimated and diffuse radiation. Cosine varying collimated and diffuse radiation is considered in detail. The solution for the cosine varying collimated radiation model is used to construct the solutions for the other boundary conditions. The two-dimensional integral equations are reduced to one-dimensional equations by the method of separation of variables
