Abstract

In this paper, a recently developed wave-vector-frequency-domain method for nonlinear wave propagation is modified and verified by underwater experiments. An improved numeric scheme is proposed that increases the accuracy from first-order to second-order, thereby allowing for a larger step-size and reduced computation time. A specially designed focused transducer was used to generate short high intensity pulses. 2D scans were conducted at a pre-focal plane, which were later used as the input to the numerical model to predict the acoustic field at other planes including the focal plane. Good agreement was observed between the simulation and experiment.
