Appendix B. Sound Propagationin a Wedge with ImpenetrableBoundaries

The determination of the sound field in a wedge with impenetrable boundaries is of interest to us for several reasons. First, this environment is a good first approximation to realistic ocean conditions found in continental slope and shelf regions. Second, a combination of Fourier transform, eigenfunction expansion, and endpoint methods enables us to obtain an exact, closed form solution to this problem for arbitrary wedge angles (cf. Prob. 4.6). Third, we can use this exact solution as a benchmark for evaluating approximate solutions for laterally varying environments [Graves et al., 1975]. The early work on this problem was performed by Bradley and Hudimac [1970].
