Efficient temporal high-order staggered-grid scheme with a dispersion-relation-preserving method for the scalar wave modeling
Staggered-grid finite-difference (FD) method is widely used to solve the wave equation for the numerical seismic modeling, and it is a key step of the advanced seismic imaging and inversion problem. However, the conventional FD method is prone to instability and dispersion error due to the insuffici...
