Finite-difference modeling of 2-D wave propagation in the vicinity of dipping interfaces: a comparison of anti-aliasing and equivalent medium approaches

Erik F. M. Koene, Jens Wittsten, Johan O. A. Robertsson

Finite-difference (FD) modeling of seismic waves in the vicinity of dipping interfaces gives rise to artifacts. Examples are phase and amplitude errors, as well as staircase diffra…

Removing numerical dispersion from linear evolution equations

Jens Wittsten, Erik F. M. Koene, Fredrik Andersson +1

We describe a method for removing the numerical errors in the modeling of linear evolution equations that are caused by approximating the time derivative by a finite difference ope…
