Gopal, Venkatesh and Ramakrishna, Anantha S and Sood, AK and Kumar, N (2001) Photon transport in thin disordered slabs. In: Pramana Journal of Physics, 56 (6). pp. 767-778.
We examine using Monte Carlo simulations, photon transport in optically thin slabs whose thickness L is only a few times the transport mean free path l*, with particles of different scattering anisotropies. The confined geometry causes an auto- selection of only photons with looping paths to remain within the slab. The results of the Monte Carlo simulations are borne out by our analytical treatment that incorporates directional persistence by the use of the Omstein-Uhlenbeck process, which interpolates between the short time ballistic and long time diffusive regimes.
