A Split-Step Pade Solution of 3D-PE Method for EM Scattering from PEC Targets
Keywords:
Electromagnetic scattering, parabolic equation method, split-step PadeAbstract
In this paper, the split-step Pade scheme is introduced to solve the three dimensional parabolic equation for EM scattering problems. By implementing the finite differential method, the calculation can be taken from plane to plane along the paraxial direction and a sparse-matrix equation needs to be solved in each transverse plane. In this way, the computational resources can be saved significantly when compared with the rigorous numerical methods. Numerical results demonstrate that the proposed method can obtain accurate results at wider angles up to 45°.
