Dispersion-corrected compact finite difference discretizations for the elastic Helmholtz equation in two and three dimensions

Rachel Yovel, Eli Turkel, Eran Treister

We develop a family of compact, dispersion-corrected marker-and-cell (MAC)-based finite-difference discretizations for the elastic Helmholtz equation. While dispersion correction i…
