Аннотация

Contrary to the problem of scattering of electromagnetic
waves from a Hertz dipole located over an impedance
wedge, the corresponding acoutic problem is explicitly
solvable (i.e. by quadrature). In this work we study diffraction
of a spherical acoustic wave due to a point source, by an
impedance wedge. In the exterior of the wedge the acoustic
pressure satisfies the stationary wave (Helmholtz) equation
and classical impedance boundary conditions on two faces
of the wedge, as well as Meixner’s condition at the edge and
the radiation conditions at infinity. Solution of the boundary
value problem is represented by a Weyl type integral
and its asymptotic behavior is discussed. On this way, we
derive various components in the far field interpreting them
accordingly and discussing their physical meaning.
