Diffraction of electromagnetic waves by three-dimensional ideally conducting bodies in a magnetodielectric envelope

A numerical method of solving the problem of the diffraction of electromagnetic radiation by structures which are an ideally conducting body of arbitrary shape in a uniform magnetodielectric envelope is proposed. The method is implemented in the form of a program for calculating the components of the diffraction field of structures with different geometrical and electrodynamic parameters. Some results of numerical investigations, carried out to investigate the effect of deviations of the shape of the structure from axisymmetrical on the energy characteristics of the scattered field, are presented.

Diffraction of electromagnetic waves by ultrasonic waves in an anisotropic medium. I

Summary The theory of diffraction of electromagnetic waves by an ultrasonic wave in a crystal is discussed above. Expressions are obtained for the diffraction field in the near and the far zones. In the near zone the system is shown to be describable by the scattering matrix S of a 2(N+1)-pole, thus enabling the matrix method of network theory to be used for in vestigating different kinds of cascade connection of such systems. The expressions obtained contain the classical formulas of scalar diffraction in an isotropic layer as particular cases.Izvestiya VUZ. Radiofizika, Vol. 9, No. 1, pp. 16–32, 1966

Diffraction of plane waves by a black wedge

The scattering of plane waves by a black wedge is examined. Two methods are considered for the solution of the problem. A closed-form series solution is derived by performing the technique of the separation of variables using boundary conditions of Macdonald. The second approach is the method of the modified theory of physical optics. The results are compared numerically.     

Diffraction of plane electromagnetic waves by a wedge with perfect mixed anisotropic conductivity sides in a chiral medium

The Sommerfeld–Malyuzhinets integral method is used to solve the problem of the diffraction of plane circlepolarized electromagnetic waves normally incident on the edge of a wedge with the sides possessing perfect mixed anisotropic conductivity, which is immersed in an isotropic chiral medium.
