%X A parallel algorithm via Element Level Vector Finite Element Method(ELVFEM) and Adaptive Multilevel Fast Multipole Algorithm(AMLFMA) is introduced. In this algorithm the calculation of finite element method can be finished at elementary level and no need to form the global coefficient matrix. By expanding the basis functions and testing functions with Dirac functions on different position, the integration calculation of the multilevel fast multipole algorithm can be simplified and transformation procedure can be calculated by FFT. Combining this algorithm with Asymptotic Wave form Evaluation (AWE) technique, the RCS of electrically large coated scatters can be calculated fast. The numerical results show the effectiveness of the presented parallel algorithm.
