VTI Media qP-wave Equation Using ONAD Method

The qP-wave equation is one of extremely important question in seismic exploration, seismology, and so on. However, its poor stability, the traditional finite difference scheme for qP-wave equation modeling suffer instability easily and numerical dispersion seriously. This paper propose a novel difference scheme for qP-wave simulation, named ONAD method. The numerical results demonstrate that, relative to LWC, the ONAD method for qP-wave has obvious advantages. It's suitable for qP-wave modeling.
