Modeling the scattering of electromagnetic waves on structures in the form of a cube

To date, among the various applied tasks in electrodynamics, it is possible to note the development of various approaches aimed at evaluating and studying the scattering characteristics of various electrodynamic objects. Among them, three-dimensional objects can be distinguished, which include flat surfaces and angular structures. Their contribution to the levels of electromagnetic fields in certain directions can be quite noticeable. In order to correctly solve the problem of scattering of electromagnetic wave scattering characteristics, it is necessary to rely on appropriate methods. At the same time, it is necessary to minimize possible errors, but the three-dimensional problem in question needs to be solved in a relatively short time. In this paper, the construction of a technique related to the determination of the scattering characteristics of a structure in the form of a cube is carried out. This is due to the fact that such structures are part of a large number of modern technical facilities, this must be taken into account during their design. To solve this problem, the method of integral equations was chosen. The results of the simulation are presented. A comparison with experimental data is carried out, and it is shown that the solution converges. A comparison with the characteristics of the Huygens cube is also carried out.
