In the paper, the solution method for the problem of electromagnetic waves scattering by cylinder bodies is given. The method is based on 2*piperiodicity property of functions describing the parameters and distributions of fields and currents on cylinder bodies. The method advantage is the possibility ...

The Fourier coefficients of the vector function equal to the current density on the mirror metal and the tangent component of the electrical vector on the geometric surface, complementing the surface of the mirror to close in some complete function system. Using these coefficients, the series for the given vectorfunction, converging to the L

Tags: scattering , electromagnetic wave , antenna , Fourier Path: Home / Publications / Archives The method of solving problems of diffraction on nonRayleight 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...
