Abstract :
A. Bayliss et al. (1982) (BT) have proposed an arbitrary order approximation based upon the Wilcox (1956) spherical wave function far-field expansion, for the case of a circular or spherical boundary with the source located at the center. In the present work, the BT-type representation is generalized to the case of an arbitrary convex boundary, with the curvature explicitly incorporated. Several possible implementations are compared.<>
