Analytical Green's function of the radiative transfer radiance for the infinite medium

Abstract:
An analytical solution of the radiative transfer equation for the radiance caused by an isotropic source which is located in an infinitely extended medium was derived using the P{N} method. The results were compared with Monte Carlo simulations and excellent agreement was found. In addition, the radiance of the SP{N} approximation for the same geometry was derived. Comparison with Monte Carlo simulations showed that the SP{N} radiance, although being more exact than the radiance derived from diffusion theory, has relatively large errors in many relevant cases.
