Ray method in seismology
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). The characteristics of the eikonal equation can be identified … See more Assume that the ray is incident on a curved interface Σ(xi ) = 0 at a point Q. We denote by the unit normal to Σ at Q. The slowness vector of the ray of a generated … See more The solution of a ray tracing system with specified initial conditions is usually called initial value ray tracing.
