Impulse response of a density contrast wedge: Practical implementation and some aspects of its diffracted component

Abstract Davis and Scharstein have recently derived a complete solution for the impulse response of a density contrast wedge (Davis AMJ, Scharstein RW. J. Acoust. Soc. Am. 1997, 101, 2821–1835). However, the general solution given as a sum of residues, reduces to a closed form only for a discrete set of wedge angles. To circumvent this limitation and make the solution available for arbitrary angles, the explicit form for the residues is provided and the numerical implementation of the solution is discussed. The solution is then applied to the analysis of the diffracted field and physical aspects are analyzed. ©
