Complex directional antenna consists of separate near-omnidirectional antennas (radiating elements) positioned in the space and driven by high-frequency …

Wave diffraction by a stripline array with passive loads

The algorithm of estimating the density of surface magnetic current induced on the array aperture has been obtained as a result of the rigorous solution of the problem of plane wave diffraction on a double periodic array of stripline elements of any shape with passive loads.

Mutual relation in convex cylindrical antenna arrays of arbitrary form composed of aperture radiators

Based on the asymptotic diffraction theory methods, the problem of determining the near field of the convex cylindrical antenna array composed of aperture radiators is reduced to the boundary value problem in the single cell of the array, which is solved using the Galerkin method....

Diffraction problems for surfaces with radio absorbing cover

The principal directions of radio absorbing materials and coatings used to solve 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.

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 ...

Boundary value problems and diffraction of waves at surfaces with a variable admittance

The problem of diffraction of electromagnetic waves on a curvilinear surfaces with piecewise continuous admittance (impedance) boundary conditions, particularly on open-ended metallic surfaces is considered. It is shown that the coefficients of Fourier kind for some ...
