The three-dimensional vector parabolic equation (PE) method was used for the fast analysis of the electromagnetic scattering with reasonable accuracy. The algorithm was marched from plane to plane along some preferred directions so that the computational load could be reduced significantly. However, large errors will be introduced for cavities with the multiple scattering. In this paper, the vector parabolic equation method combined with the multilevel fast multipole method (MLFMM) is presented for the analysis of the electromagnetic scattering from a cavity. Numerical results demonstrate that the proposed technique can efficiently give reasonably accurate results for the cavities when compared with the conventional PE method.
