Solving of applied problems concerning different physical processes often involves search for analytic solutions to the boundary value problems of mathematical physics. From this viewpoint, the use of the variable separation method is one of possible …

When studying stationary and wave processes of different physical nature (oscillations, heat-conductivity, diffusion, etc), we often come to Laplace and Helmholtz equations:

In electrodynamics, U represents the electric field potential, created by charges or currents provided that there are not volume charges in the region. To illustrate the application of the generalized Fourier method of variable separation (GFM), we consider the internal hybrid boundary problem for these equations in rectangular domain on the plane. The geometry of the task is depicted in Fig. 1…

In section of “Publications-Archive” the “The Algorithm and Results of Calculating the Radiation Patterns of Antenna Arrays on an Infinite Wedge” archival article is published. Authors: Z. K. Kudrya, E. M. Privalov.

In the article Green's tensor function has been used as a basis to get the expression for the radiation pattern of a rectangular waveguide radiator array located on an infinite perfectly conducting wedge. The obtained expression has been analyze, which has made it possible to calculate the integral in a complex plane with the help of the saddle-point method.
