Fast algorithms for elastic-wave-mode separation and vector decomposition using low-rank approximation for anisotropic media

Examples

This section contains four examples. They are for 2D and 3D two-layer models, the SEG/Hess VTI model and the BP 2007 TTI model, respectively. We use 10th-order finite-differnece algorithm for elastic wavefield extrapolation. To accurately compare the used CPU times, algorithm parallelization is not considered for wave mode separation and vector decomposition.
