Our next analytical example is a horizontal reflector in a homogeneous
VTI (vertically transverse isotropic) medium. As derived in Appendix
E, the approximation coefficients, under the assumption of the
acoustic approximation of Alkhalifah (1998), take the form
Equation 2 with coefficients given by
equations 34-36 is precisely equivalent to the
traveltime approximation suggested previously by
Fomel (2004). Fomel (2004) shows comparisons
with alternative non-hyperbolic approximations, which demonstrate
superior accuracy of equation 2 in case of strongly
anisotropic media.
