| 英文摘要 | This article provides a technique to model seismic wave propagation in complex media using convolution differentiator method based oil Shannon singular kernel theory. The high accuracy of the differentiator has been demonstrated through comparisons with numerical results computed by staggered-grid finite difference method. Numerical tests Suggest that the differentiator allows sufficient accuracy even in high wave-number domain. Dispersion and stability condition of the method in velocity-stress equation are also thoroughly discussed Experiment in homogeneous medium in velocity-stress equation are also thoroughly discussed. Experiment in homogenous medium shows that the 9-point scheme of this differentiator can achieve analytical accuracy. The application of this differentiator to model seismic wave propagation in homogenous layered medium and complex medium also shows high accuracy and robust stability. These appealing characters of this Improved method would make It effective to model seismic wave propagation in complex media. |
