论文名称：Time-space domain staggered-grid finite difference method for porous media

发表刊物：SEG Technical Program Expanded Abstracts 2013

摘要：Finite difference methods have been widely used in seismic
modeling; however, they generally suffer from numerical
dispersion problems. Based on the dispersion relation for
porous media, we develop the time-space domain and the
weighted average time-space domain high-order staggered-
grid finite difference (SFD) method to suppress the numeri-
cal dispersion. Compared with the conventional SFD meth-
od, the proposed method has better accuracy with disper-
sion analysis and numerical modeling under the same dis-
cretization.
