Ribodetti (Géosciences Azur - IRD) J. Virieux (Géosciences Azur - UNSA) & S. Operto (Geosciences Azur - CNRS) SUMMARY We present a 2D finite-difference frequency-domain method for modeling acoustic wave propagation in TTI media. The numerical method relies on a parsimonious staggered-grid method implemented in the frequency domain. Discretization of the differential operators is performed along 45° rotated directions. We applied this discretization strategy to the anisotropic acoustic wave equation for TTI media derived by Zhou (2006). The finite-difference stencil ..
