Résumé

2.5D modeling is appealing to speedup calculations when physical properties are invariant in one horizontal dimension. The discrete Fourier transform imposed by the 2.5D geometry implies the selection of a particular set of wavenumbers to sample the out-of-plane dimension. In this article, we derive simple criteria for the number and the spacing between the wavenumbers in order to apply the 2.5D configuration to frequency-domain modeling. To show the efficiency of the derived criteria, we use finite-difference methods to obtain full 3D wavefront for viscoelastic media.
