【 摘 要 】

Local order of scattering medium is essential in multiple-scattering problem. It causes coherent effects in light scattering character. We consider scattering phase function computation for growing ordered structure, i.e. cluster formation. The computational results illustrate a deformation of scattering phase function and its transformation during the growth of particle cluster as well as the energy and peak characteristics of this process, which indicate the possibility to determine the generalized equations for scattering phase function depending only on form- and structure-factor. We study multiple scattering on structured media consisted of different clusters using Monte Carlo numerical approach. The cluster phase function has direct impact on scattered radiation, moreover, for media consisted of different clusters the middle-cluster approach is estimated.
