| 英文摘要 | Absorption and dispersion in earth media is an issue we should consider for wavefield simulation. In this paper, we present a time-domain numerical modeling algorithm for acoustic wave in inhomogeneous viscoelastic medium. On one hand, to describe the attenuation effect we use the constant-Q model, which can be frequency-independent. On the other hand for the wavefield modeling engine, we utilize the grid method, which uses irregular, unstructured grid to simulate acoustic wave propagation in non-uniform viscoelatsic media. |
