Karazin popup.description2 A research object is diffraction of hertzian waves on axisymmetrical and flatness parallel reflectors, being the elements of antenns, radio-telescopes, waveguides and other high-frequency devices. An aim of work is a construction of the effective fast-acting high-fidelity programs IBM called to decide the tasks of diffraction of the electromagnetic field on trivial - parallel surfaces and surfaces of rotation. Realization of calculable experiments. verification of authenticity of the got results.. A method of researches is creation of high-efficiency numeral methods of decision of the border integral equalizations got from regional equalizations of Максвелла. Use for these aims method of discrete features. On the basis of these methods there are development and debugging of complex of the programs IBM and realization of numeral experiments. General raising of task and her actuality: Taking of tasks of diffraction of the electromagnetic field to integral equalizations results in reduction of dimension of the got tasks, and, consequently, assists the construction of effective methods of their decision. On the department of mathematical physics and calculable mathematics of mechanic mathematical faculty of the Kharkov national university of the name V. N. Karazin by the professors of Gandel Yu. V., Scherbina V.A. and their followers are work out physical models resulting in similar equalizations in the different areas of physics, in particular, in the tasks of the guided thermonuclear synthesis, diffraction, physics of plasma. Effective quadrature formulas are built for a calculation singular and hypersingular интегро - differential equalizations, that serves as basis for the construction of high-fidelity fast-acting models of their numeral decision. On the basis of got models the computer programs are created for IBM, their debugging is conducted. Large attention is spared to verification of to authenticity.
