description: The object of research is an absorber of the Â«Ð¨Ð¢ÐÐÐ¬-100Ð30Â» type. The purpose of the work is to prescribe a method for the correct calculation of the reflection coefficient from flat and pyramidal coatings. An analytical solution for the reflection of electromagnetic waves from a flat layer of omega composite is analyzed, and an analytical solution for the reflection coefficient at different angles from the flat air/dielectric boundary on the metal is derived. A drawing set of tools was mastered in the ANSYS HFSS program, and an algorithm for recreating the pyramid was prescribed. The literature about the methods of calculating fields in HFSS has been studied. Based on it, an algorithm for calculating the reflection coefficient at different angles of incidence for different surfaces was prescribed. An experiment was performed to measure the reflection coefficient at different angles of incidence for a layer of a flat absorber on a metal. When comparing the results of analytics, modeling, experiment and characteristics from the manufacturer, a conclusion was made about the effectiveness of modeling. Information about the properties of absorbers is scarce, especially about the dependence of the reflection coefficient on the angle of incidence. The developed method is well suited for the selection of material characteristics in the analysis of created radio-absorbing coatings and in the development of new ones. Open educational resources and information search and analysis programs were used. Automated development tools were used: a vector spectroanalyzer with results processing on a computer. The software is applied: the package of the finite element method.
