Explicit finite difference method has been widely used for seismic modeling in heterogeneous media with strong discontinuities in physical properties. In such cases, due to stability considerations, the time step size is primarily determined by the medium with higher wave speed propagation, resulting that the higher the speed, the lower the time step needs(More)
Acoustic wave modeling is widely used to synthesize seismograms theoretically, being the basis of the reverse time migration strategy. Explicit Finite Difference Method (FDM) is often employed to find numerical solution of this problem and in this case, spatial discretization is related to the shortest wavelength to be captured and temporal discretization(More)
