Lysechko V. Diffraction of acoustic waves by conical shapes

The analytical regularization technique for solving of the plane wave diffraction problems from soft and rigid conical shapes with circular edges at arbitrary incidence angle and geometric parameters of scatterers is developed. The new regularization operators for solving of diffraction problems on soft and rigid circular discs and apertures at arbitrary incidence angles are obtained. The formation of acoustic fields diffracted from fragments of conical surfaces, from their geometric parameters and incidence angles in a wide frequency range, including the resonance, the transition and the region of geometrical acoustics is found out.
