摘要：
This paper presents an efficient leapfrog implementation of the 2-D split-field (SF) FDTD method for solving problems of the oblique incident plane wave on periodic structures. By adopting the modified SF method, Peaceman-Rachford scheme, one-step leapfrog scheme and ShermanMorrison formula, the proposed SF method is implemented in the much simpler scheme than traditional SF method. Furthermore, the Courant-Friedrich-Levy (CFL) stability condition of the proposed method is weaker. The accuracy and efficiency of this method are verified by numerical results.
