On the Sound Field Generated by Membrane Surface Waves on a Wedge-Shaped Boundary

A semi-infinite membrane, joined to a rigid surface at an arbitrary angle, supports incident unattenuated surface waves. A compressible fluid is contained within the two semi-infinite boundaries and the resultant reflected surface-wave amplitude and the scattered acoustic field is sought. A method o...

Zusammenfassung:	A semi-infinite membrane, joined to a rigid surface at an arbitrary angle, supports incident unattenuated surface waves. A compressible fluid is contained within the two semi-infinite boundaries and the resultant reflected surface-wave amplitude and the scattered acoustic field is sought. A method of solution is presented for wedge angles(2p + 1) π/2q, p and q integers, and the exact solution is obtained for an acute angle of ¼π.
