Abstract

A model of a spherically focused piston transducer is developed in terms of boundary diffraction waves. The model represents the radiated pressure in terms of a direct wave and a one-dimensional edge wave integral. This decomposition allows the efficient calculation of the transducer beam in a form previously available only for a planar transducer. Numerical results for the simulation of the entire wave field of a transducer are given to illustrate the effectiveness of the formulation.
