On the scattering of the plane wave by transparent wedge

It is proved in the paper, that the problem of scattering of the plane wave by transparent wedge, if the radiation conditions it should be mean in the form: it necessary to subtract from the solution the incident wave, all reflected and refracted waves. The remainder is to satisfy the radiation condition in integral form. The problem is scalar, the velocity of wave inside and outside of the wedge are not equal, the wave process is described by the classical Helmholtz equations, conjugation boundary condition take place on the sides of the wedge.
