Abstract
We derive separable approximations to orthorhombic dispersion relations that allow accurate and efficient modeling of P-waves. These allow extension to orthorhombic media of generalized pseudospectral methods previously used for modeling and reverse-time migration of P-waves in transversely isotropic media.
