3D Lomax rays and its application for acoustic wavefield simulation in complex media

Abstract
We present a simple and robust approach for calculating frequency-dependent rays in three dimensional media. The proposed method simulates propagation of locally plane fragment of a wavefront. Ray properties depends on velocity distribution in some sub-volume around the ray and on wavelength in each point. Numerical experiment demonstrates the applicability of the proposed method to calculate travel-times and ray-based acoustic wavefields in complex 3D environments with the presence of slat intrusion.
