| 英文摘要 | Frequency domain numerical modeling is the basis of frequency domain full waveform inversion. The accuracy of forward modeling seriously influences the result of inversion. In this paper, we develope a new method for frequency domain scalar wave equation to improve numerical simulation accuracy. The new method uses a rhombus stencil to approximate the Laplacian term and uses the weighted average of the difference scheme stencil points to approximate the mass acceleration term. Compared with the conventional stencil and the optimal square stencil, the numerical dispersion analysis shows that the new rhombus stencil can significantly decrease the grid points of per wavelength and reduce the numerical dispersion. Accuracy analysis demonstrates that the results of the new rhombus stencil are in best agreement with the analytical solutions relative to the other stencils in frequency domain and time domain. Two numerical examples are used to demonstrate the effectiveness of the new rhombus stencil for frequency domain scalar wave equation. (C) 2019 Elsevier B.V. All rights reserved. |
