SMART: dissipative absorbing layer technique for general elastodynamics equations. Application as S-waves filter in acoustic TI media

Résumé

Seismic imaging methods such as FullWaveform Inversion (FWI Virieux and Operto [38], M´etivier et al. [30, 28]) or Reverse Time Migration (RTM Baysal et al. [6]) require accurate modeling engines for the propagation of seismic waves in infinite or semi-infinite media. To this end, the use of efficient absorbing boundary conditions is mandatory. Moreover, one should be sure that the modeling engine will provide always an answer at each iteration of the inversion and of the migration. The stability is, therefore, a very important property of absorbing conditions.
