On modeling of the radiative electromagnetic field in polydisperse media of a closed-cell structure

Algorithms for supercomputer modeling of the radiation electromagnetic field in heterogeneous materials of a complex fine disperse structure are constructed. A geometrical model of heterogeneous medium with application of algorithms of Stillinger-Lubachevsky for multimodal structures is created. The model includes a system of detectors for statistical evaluation of functionals on the space of solutions of the photon-electron cascade transport equations. The results of demonstration calculations of the electromagnetic field are presented. The results of calculations showed that the spatial distribution of the radiation electromagnetic field has a sharply inhomogeneous structure caused by the presence of boundaries of materials with different radiation properties.
