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…

Perfect partial reconstructions for multiple simultaneous sources
Jens Wittsten, Fredrik Andersson, Johan Robertsson +1
A major focus of research in the seismic industry of the past two decades has been the acquisition and subsequent separation of seismic data using multiple sources fired simultaneo…
