In this study, we present a new frequency-dependent ray- tracing method that aims to overcome some of the limitations of standard high- frequency ray tracing in complex velocity models that contain complex interfaces. Our method is based on a frequency-dependent Snell’s law, which is defined by localization of the Kirchhoff integral formula around a inter- face location of interest. With a modest increase in computa- tional cost, the method presented captures the wave kinemat- ics that are comparable to finite-difference wave propagation with higher fidelity while staying within the ray-tracing frame- work, without requiring processing or alteration to the original model. We present comparison of our method with finite- difference wave propagation in numerical simulations.
