Title: The Solving of Acoustic Wave Equation in Two Dimensional Complicated Medium with Ray Tracing Technique
Abstract: In this paper, a method is developed for solving the a-couslic wave equation with ray tracing technique. It base on acoustic wave equation and the condition of high frequency approximation. The acoustic wave that is emitted in practice is characteristic of limited frequency band, it is consider in this algorithm, so the wave ray is substituted by wave path. In order to avoid caustics phenomenon the amplitude is calculated in phase space. This method overcomes the disadvantage of usual ray tracing technique that the caustics and shade of ray are easy to appear in complicated medium. Tests show it is effective.
