A comprehensive study of the electrodynamic properties of radio absorbing materials (RAM) is inseparably connected with the task of modeling the structure of such materials. Methods of modeling the microstructures of radio-absorbing materials consider them as a combination of the constituent characteristics of the described material by the coefficients of the corresponding model equations, and the topology of the material, which is expressed by the areas of integration, where these equations are defined. The aim of the work is to develop methods for modeling RAM microstructures, which allow to provide a unified approach to the study of thermophysical and electrodynamic characteristics during their creation. The practical significance lies in the study of a unified approach to the method of analysis of coupled processes in RAM structures, based on field theory methods, which allows to investigate their thermophysical and electrodynamic processes. The area of application is the development of radio-absorbing coatings, as well as the study of the influence of their structure on the scattering-absorbing properties and thermophysical parameters. The area of application is the study of the properties of radio-absorbing coatings.
