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 “Solution to the three-dimensional problem of wave diffraction for a group of solids via the pattern equation method” archival article is published. Authors: A. G. Kyurkchan, E. A. Skorodumova.

In the article the explicit (asymptotic) solution of a problem is obtained in a case, when the scattering bodies are far enough from each other. It's established, that the obtained approximate analytical solution of a problem is suitable for calculations with an acceptable exactitude at distances between bodies down to their touch, if the sizes of bodies do not exceed a wave length of a field, incident on a group.
