Numerical simulation or forward modelling of wave propagation is a cheap and effective way to produce test data and to examine the mechanism of wave propagation. Because of the complexities of anisotropy, forward modelling is a practical means to aid the anisotropy analysis. Although a lot of work has been done on the forward modelling in anisotropic media, it rarely reaches the level of practical use. In this paper, the pseudospectral method is proposed to do the forward modelling in anisotropic media.
