Abstract:
An efficient method — inward-looking approach combined with multifrontal algorithm is proposed for solving linear equations deduced from hybrid finite element method — boundary element method(FEM/BEM)for electromagnetic(EM)problems. The coefficient of the equations formed by FEM/BEM is a matrix of partially sparse and partially full. To solve it fast, the matrix is divided into two parts by utilizing the inward looking approach. One is a sparse matrix, and the other a full matrix. The former is solved by the multifrontal method and the latter is solved by Gauss-Jordan method. Using the above technique, the radar cross section by two dimensional multilayer dielectric cylinders is computed. The results demonstrate that its calculation efficiency is much better than that of the Gauss method.
