A transversely isotropic medium with a tilted symmetry axis normal to the reflectora
The computational tools for imaging in transversely isotropic media with tilted axes of symmetry (TTI) are complex and in most cases do not have an explicit closed-form representation. As discussed in this paper, developing such tools for a TTI medium with tilt constrained to be normal to the reflector dip (DTI) reduces their complexity and allows for closed-form representations. We show that, ...
متن کاملScalar generalized-screen algorithms in transversely isotropic media with a vertical symmetry axis
The scalar generalized-screen method in isotropic media is extended here to trans-versely isotropic media with a vertical symmetry axis (VTI). Although wave propaga-tion in a transversely isotropic medium is essentially elastic, we introduce an equiv-alent ‘acoustic’ system of equations for the qP-waves which we prove to be accuratefor both the dispersion relation and the po...
متن کاملDynamic and Static Green's Functions in Transversely Isotropic Elastic Media
Concise and numerically feasible dynamic and static Green's functions are obtained in dyadic form by solving the wave equation and the equilibrium equation with general source distribution in transversely isotropic (TI) media. The wave and equilibrium equations are solved by using an extended version of the Kupradze method originally developed for isotropic media. The dynamic Green's function i...
متن کاملElastic wave mode separation for tilted transverse isotropic media
Seismic waves propagate through the earth as a superposition of different wave modes. Seismic imaging in areas characterized by complex geology requires techniques based on accurate reconstruction of the seismic wavefields. A crucial component of the methods in this category, collectively known as wave-equation migration, is the imaging condition that extracts information about the discontinuit...
متن کاملViscous propulsion in active transversely isotropic media
Taylor’s swimming sheet is a classical model of microscale propulsion and pumping. Many biological fluids and substances are fibrous, having a preferred direction in their microstructure; for example, cervical mucus is formed of polymer molecules which create an oriented fibrous network. Moreover, suspensions of elongated motile cells produce a form of active oriented matter. To understand how ...
