Abstract

Frequency-domain finite-difference solution of the scalar wave equation is the kernel engine for FWI and RTM. In this study, we proposed a computationally efficient approach to cope with numerical dispersion error. To do so, a new 9-point scheme is developed, adapted from the exact finite-difference family of the frequency-domain schemes, which interpolates the plane wave solution in the span of the compact 9-point stencil. Dispersion analysis and numerical simulations confirm that this approach is more accurate than the 25-point scheme, while preserving the low-cost benefits of the 9-point scheme.
