KRYLOV, V.V. and SHANIN, A.V.,1993. Scattering of an acoustic wedge wave by a shallow notch. Acoustical Physics, 39 (2), pp. 155-158.
The scattering of an acoustic wedge wave by a shallow notch is investigated in the first perturbation
approximation. It is shown that scattering goes into all wedge modes. Analytical equations are derived for the
amplitudes of the scattered waves.
