The method is developed to model the three dimensional (3D) terrain effect of the electromagnetic fields of the artificial source in the frequency domain. By vector integral theory and boundary conditions, the electromagnetic fields in the air and earth medium are transformed into two vector integral equations just related to the topography. The integral related to the topography is then decomposed into a series of integrals in the triangular element.The electromagnetic fields in the triangular element are decomposed into two parts : the electromagnetic fields in the unlimited air space and in the earth medium. The linear equations come from vector integral equations can be solved by SSOR. |
