摘要：
We present a method for computation of frequency-dependent rays which are governed by the exact eikonal equation. First, the phase velocity related with a frequency-dependent ray can be analytically expressed through an iterative perturbation method. Then, a triangular grid-based network ray tracing method is developed and used to calculate traveltime field in a discretized medium. The results of simulated data are shown.
