Approaches to mathematical modeling of coatings that protect against electromagnetic radiation in the soft x-ray range

The objects of study are composite structures that protect agaist electromagnetic radiation in the soft X-ray range. The purpose of this work is to propose approaches to the mathematical modeling of coatings based on these structures, to calculate the reflection and transmission characteristics of a homogeneous plane wave incident at different angles on such coatings. Research methods - electrodynamic modeling, graph theory, three-dimensional electromagnetic modeling in CAD. Mathematical models of multilayer structures obtained on the basis of the electrodynamic approach and using graph theory, the results of calculations of the reflection and transmission characteristics of a homogeneous plane wave incident at different angles on such structures are presented. The prospects for the use of film coatings with air holes are considered. The results obtained in the course of the work may be used to create coatings that protect electronic equipment from the effects of X-rays.
