文摘Transparent boundary conditions(TBCs)for anisotropic vertical transverse isotropic VTI medium are formulated for the axially symmetric case.The high accuracy of the derived TBCs and their long-time stability are demonstrated in numerical experiments.The TBCs are represented in terms of the vertical component of the velocity vector and tangential component of the stress tensor that facilitates the easy implementation of the boundary condition into the finite-difference staggered-grid scheme.
