Lowrank finite-differences and lowrank Fourier finite-differences for seismic wave extrapolation in the acoustic approximation |

where is the P-wave phase velocity in the symmetry plane, is the P-wave phase velocity in the direction normal to the symmetry plane, is the anisotropic elastic parameter (Alkhalifah and Tsvankin, 1995) related to Thomsen's elastic parameters and (Thomsen, 1986) by

and and stand for the wavenumbers evaluated in a rotated coordinate system aligned with the symmetry axis:
