An analysis of 3D anisotropic–viscoelastic forward modeling and dissipation [PDF]

open access: yesJournal of Geophysics and Engineering, 2015
The anisotropic?viscoelastic wave equation is a generalized expression of a transversely isotropic?viscoelastic medium. The viscoelastic horizontal?tranverse isotropic (HTI) medium is a special case. Considering the horizontal symmetry axis of viscoelastic HTI media, we develop elasticities and wave equations for preserving its transverse isotropy.
