Numerical simulation of coherent effects under multiple scattering of linearly polarized light

Using a combination of the stochastic technique and the iteration procedure of the solution to BSE, numerical computational method is developed for stochastic modelling of coherent effects in a multiple scattering medium. It is shown that additional phase-related factors in framework of ladder diagrams are equivalent to multiplication of the statistical weights by corresponding factors after each scattering event during the random walk of a photon packet. The Monte Carlo technique is generalized for the simulation of the coherent backscattering and temporal field correlation function of optical radiation. The developed model yields qualitative results that are ready for direct comparison against theoretical predications.
