The ray theory method is computationally rapid and extends to range-dependent problems. Furthermore, the ray traces give a physical picture of the acoustic paths. From the first equation of the basic recurrence system of equations of the elastodynamic ray method, we obtain the approximate HF separation of the seismic wave field in a smoothly varying inhomogeneous medium into two waves, called compressional (P) and shear(S) waves. The eikonal of the P wave … See more The eikonal equations may be solved by means of characteristic trajectories (characteristics for short).
