Abstract

Summary

We propose a new velocity approximation that has the same functional form for both phase and group velocities in transversely isotropic and orthorhombic media. The approximation parameters are defined in symmetry planes only. Proposed approximation has 5 parameters for transversely isotropic medium (2D case) and 12 parameters for orthorhombic medium (3D case). Approximation is exact for phase velocity in transversely isotropic medium and in all symmetry planes for orthorhombic medium.
