Item Open Access Coherent effects in multiple scattering of linearly polarized light.(Springer Science Business Media, 2005-04-01T00:00:00Z) Kuzmin, Vladimir L.; Meglinski, I. V.; Churmakov, D. Y.Comparing the stochastic Monte Carlo technique with the iteration procedure for solving the Bethe–Salpeter equation in the framework of numerical simulation, the time correlation function and the interference component of the coherent backscattering of a linearly polarized light wave in a multiply scattering medium are calculated. The results of the simulation agree well with theoretical results obtained by generalizing the Milne solution, as well as with experimental datItem Open Access Coherent multiple scattering effects and Monte Carlo method(Springer Science Business Media, 2004-02-01T00:00:00Z) Kuzmin, Vladimir L.; Meglinski, I. V.Based on the comparison of the iteration procedure of solving the Bethe-Salpeter equation and the Monte Carlo method, we developed a method for simulating coherent multiple-scattering effects within the framework of a unified stochastic approach. The time correlation function and the interference component were calculated for the coherent backscattering from a multiply scattering medium.Item Open Access Monte Carlo simulation of coherent effects in multiple scattering(Royal Society, 2005-01-08T00:00:00Z) Meglinski, I. V.; Kuzmin, Vladimir L.; Churmakov, D. Y.; Greenhalgh, D. A.Using a combination of the stochastic Monte Carlo technique and the iteration procedure of the solution to the Bethe-Salpeter equation, it has been shown that the simulation of the optical path of a photon packet undergoing an nth scattering event directly corresponds to the nth-order ladder diagram contribution. In this paper, the Monte Carlo technique is generalized for the simulation of the coherent back-scattering and temporal correlation function of optical radiation scattered within the randomly inhomogeneous turbid medium. The results of simulation demonstrate a good agreement with the diffusing wave theory and experimental results.Item Open Access Numerical simulation of coherent effects under multiple scattering of linearly polarized light.(Springer Science Business Media, 2004-01-01T00:00:00Z) Kuzmin, Vladimir L.; Meglinski, I. V.The time correlation function and the interference component of the coherent backscattering from a multiple-scattering medium are calculated in the framework of the Monte Carlo technique. By comparing the stochastic Monte Carlo technique with the iteration procedure of solving the Bethe–Salpeter equation, it is shown that the simulation of the optical path of photon packets that have experienced n scattering events is exactly equivalent to calculating the nth-order ladder diagram. Using this equivalence, the Monte Carlo technique is generalized for simulation of the time correlation functions and coherent backscatteriItem Open Access Stochastic Modelling of Coherent Phenomena in Strongly Inhomogeneous Media.(Springer Science Business Media, 2005-07-01T00:00:00Z) Kuzmin, Vladimir L.; Meglinski, I. V.; Churmakov, D. Y.A procedure of numerical simulation for coherent phenomena in multiply scattering media is developed on the basis of the juxtaposition of a Monte Carlo stochastic method with an iterative approach to the solution of the Bethe- Salpeter equation. The time correlation function and the interference component of coherent backscattering are calculated for scalar and electromagnetic fields. The results of simulation are in good agreement with experimental results, as well as with theoretical results obtained by generalizing the Milne solution.
