In the paper we consider the processes of scattering of electromagnetic waves on the objects with complex shape. Different types of methods, depending from the wavelength are analyzed. The main steps of the solution of the problem of scattering of electromagnetic waves on the object with complex shape are discussed. The possibilities of use the parallel approach for calculation is discussed. Based on integral equations method developed an algorithm for the numerical solution of the problem, with the help of parallel algorithm of the method the Gauss described the process of parallelization. Some results of calculations are given. © 2015 Taylor & Francis Group, London.

In the paper we consider the processes of scattering of electromagnetic waves on the cavities with complex shape. The particularities of the method of moments are given. The advantages of the method of integral equations are shown. In solving the integral equation by the method of moments as basis functions chosen us piecewise constant functions and test functions-δ-Dirac function. The universality of the considered algorithm is due to the fact that for the calculation of the scattering characteristics of perfectly conducting hollow structures of various forms necessary to change the outline of a structure when programming with regard to the necessary steps of the partition—the main steps of the algorithm are the same. Some results of calculations of some types of hollow structures are shown. © 2015 Taylor & Francis Group, London.

The work discusses an algorithm based on a ray tracing method. The use of the proposed algorithms improves the calculation accuracy within a specified error with due account for mirror and diffusion reflections, as well as diffraction loss during electromagnetic wave propagation.

This paper describes the methods for estimation the propagation characteristics of electromagnetic waves in Wi-Fi communications. Using mathematical relationships below, an algorithm was built for estimating the degree of attenuation of radio waves in the urban environment. Considered algorithm ignores natural interference caused by the propagation of electromagnetic waves (including broadband). The program was created for solving the problem of wave propagation. The testing software were hold. The system requirements for the operation of this software were present. © 2015 Taylor & Francis Group, London.
