| Abstract: | The numerical calculation methods for Green's function and its gradients with forward speed in the frequency domain are presented in this paper.The highly oscillating and slow attenuation,which are characteristic of Green's function and its gradients,are removed in this method so that the accuracy and efficiency are improved on a large scale. |
| |
| Keywords: | Green function and its gradients forward velocity high oscillation slow attenuation |
