The quantitative analysis of physical processes that occur during the excitation of planar and rectangular waveguides with an infinite flange, with a bending flange and an array of planar and rectangular waveguide radiators on an infinite plane and on an infinite wedge has been carried out. The quantitative analysis of physical processes that occur during the excitation of planar and rectangular waveguides with an infinite flange, with a bending flange and an array of planar and rectangular waveguide...

... Helmholtz equation and also problems in aerodynamics, electrotechnics and the theory of elasticity to boundary value singular or hypersingular integral equations. Some properties of these equations were studied. The methods of calculations and the numerical solution (the discrete vortices method type and interpolation type) in the class of both absolutely integrable and non–integrable function were given for singular integrals and singular integral equations. These results served as a basis ...
