Webseveral new rays. A reflected wave enters and exits at the same angle measured to the normal of the boundary - angle of incidence equals angle of reflection. From Snell's Law, a … 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. Let us consider, e.g., the ray tracing system of Eq. 6 … See more The ray can be interpreted and derived in many ways.
