摘要：

In this paper an efficient statistical solution approach for the quantitative description of the coherent backscattering (CBS) from turbid media based on an electrical field Monte Carlo method is presented. Spherical scatterers in a semi-infinite medium, which are illuminated with a defined polarization, are investigated. In particular, different variance reduction methods are reported, applied to the CBS and implemented. The obtained results are compared with a standard Monte Carlo method (SMCM). With the help of the presented methods, it is possible to efficiently obtain the spectrally resolved CBS on the basis of a single Monte Carlo simulation. A speed comparison of the SMCM with the Monte Carlo method, which includes the variance reduction methods, is made showing an acceleration of many orders of magnitude. (C) 2022 Elsevier Ltd.
