Ray Velocity Derivatives in Anisotropic Elastic Media. Part II - Polar Anisotropy
Igor Ravve, Zvi Koren
In Part I of this study, we obtained the ray (group) velocity gradients and Hessians with respect to the ray locations, directions and the anisotropic model parameters, at nodal po…

Ray Velocity Derivatives in Anisotropic Elastic Media. Part I -- General Anisotropy
Zvi Koren, Igor Ravve
We present an original, generic, and efficient approach for computing the first and second partial derivatives of ray velocities along ray paths in general anisotropic elastic medi…
