Abstract:
The problem of diffraction of a monochromatic acoustic wave on a system of nonintersecting bodies, screens and antennas is considered. A boundary value problem for the Helmholtz equation is reduced to a system of integral equations on manifolds of different dimensions. We use the Galerkin method with a choice of piecewise constant basis functions to find the approximate solutions of the resulting system. We use subhierarchical approach to solve the problem of diffraction by scatterers irregular shapes. A series of computing experiments is conducted; the calculation results are presented in the graphic form.
