THE SIMULATION OF RADIO WAVE SCATTERING ON THE STRUCTURES WITH ABSORBING LAYER
E. V. Aleshkina
This paper describes the problem of scattering of radio waves in a complex diffraction structure having a cut absorptive coating on part of its surface. The system of integral equations in the framework of it contact density potentials, green function and the initial frequency was formed. Once solved the system of equations with the application of the relevant basis functions based on the method of moments was calculated values of the effective area of scattering at given conditions of observation. Suggestions were made on how to form a subsystem of CAD, which will provide opportunities to conduct designing of equipment with the necessary values of the scattering characteristics. As input to this subsystem, you can apply the scattering structure, the sector of observation angles, the required value of the level for the characteristics of scattering of radio waves.
