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 experimen

A common way to construct a finite difference scheme is to satisfy a desired order of approximation, typically as high as possible. For linear wave propagation problem approximation together with stability delivers convergence of the same order as ap

Operator of proposed low-reflecting boundary conditions is derived by approximation of discrete transparent boundary conditions obtained numerically. Reasonable computational costs are achieved due to sum-of-exponentials representation of occurring t
