Abstract

In this paper, we will present a modified wave-vector-frequency-domain method for predicting linear/nonlinear wave propagation in arbitrarily heterogeneous media. The Westervelt equation for heterogeneous media will be transformed into the wave-vector-frequency-domain. An implicit analytic solution based on the Green's function will be shown and can be solved by a previously developed stepping algorithm. Numerical results are compared with those of the k-space method which shows good agreement.
