Finite-difference quasi-P traveltimes for anisotropic media
The first-arrival quasi-P wave traveltime field in an anisotropic elastic solid solves a first-order nonlinear partial differential equation, the q P eikonal equation. The difficulty in solving this eikonal equation by a finitedifference method is that for anisotropic media the ray (group) velocity direction is not the same as the direction of the traveltime gradient, so that the traveltime gra...
متن کامل3D Eikonal Solvers, Part II: Anisotropic Traveltimes
In anisotropic media the direction of energy propagation is not in general tangent to the wavefront normal. On the other hand, nite di erence eikonal solvers compute the solution based on the traveltime gradient and the wavefront normal. Local convexity of the wavefronts in transverse isotropic (TI) media is studied for the eikonal solver to determine the correct upwind direction of the energy ...
متن کاملElectrostatics of Anisotropic Inclusions in Anisotropic Media
There are many ways to solve potential problems for anisotropic mixtures. The nite element method is a popular choice with great exibility that gives the solution in the entire computational domain. EEective medium approximation is a simpler option that only estimates eeective properties. Interface integral equation methods is a third class of methods that has been studied for a long time, but ...
متن کاملPtychography in anisotropic media.
This letter describes ptychography in the context of polarized light probing anisotropic specimen (i.e., showing properties of birefringence and/or diattenuation). We established an optimization strategy using a vectorial formalism. We propose a measurement scheme using a set of linearly polarized probes and linear polarization analyzers, which allows the retrieval of the full anisotropy map of...
متن کاملInterior Transmission Problem for Anisotropic Media
In recent years there has been considerable interest in the inverse scattering problem for anisotropic medium, particularly in the case of acoustic waves and electromagnetic waves. Due to the lack of uniqueness in determining the constitutive parameters, traditional methods for solving the inverse scattering problems based on the use of weak scattering approximations or nonlinear optimization t...
