Elastic-wave-equation numerical simulation using a time–space domain dispersion-relation-based staggered-grid finite-difference method

Frontiers in Earth Science
Compared to the conventional high-order staggered-grid finite-difference method (C-SFD), the time–space domain dispersion-relation-based high-order staggered-grid finite-difference method (TS-SFD) can suppress the numerical dispersion more efficiently to
