Diffraction problems for surfaces with radio absorbing cover



... the problems of scattered fields management are considered in the paper. The review of the basic methods of the task solution for the bodies of arbitrary geometry with radio absorbing materials and coating is given. The review is based on the use of impedance boundary conditions of different order. Successes of modern radio electronics

Diffraction of electromagnetic waves on a non–Rayleigh bodies with zero and impedance boundary conditions



The method of solving problems of diffraction on non-Rayleight bodies, composed of several Rayleigh bodies is explained. The scattered field is constructed as a sum of fields, created by the assemblage of multifields, each of them is located in the corresponding point of one of the composite bodies. The samples involving two tangent to the generatrix of the cylinder and two touching in the single point spheres are considered. For the former of these samples, the curves of distribution current density...
