| 英文摘要 | The crucial problems of 3D for-ward modeling using the staggered-grid finite difference method are described in detail in this paper. They are staggered-grid, discretization of integrated form of Maxwell equation, boundary condition, solving linear algebra equations and calculating 3D tensor impedance. Giving the more explicit boundary conditions and using Bi-conjugate gradients stabilized method to solve the linear algebra equation with large coefficient matrix, we get a fast algorithm of high-precision to calculate effectively electrical and magnetic fields in the whole space. This has been proved by comparing the 3D for-ward modeling solutions with analytic solution to abutting quarter-spaces, and 2D forward modeling to 2D prism using the 2D finite element method. This efficient algorithm has setup basis for research of 3D inversion. |
