Efficiency-Improved LOD-FDTD Method for Solving Periodic Structures at Oblique Incidence


This letter presents an efficiency-improved locally one-dimensional finite-difference time-domain (LOD-FDTD) method for solving the problems of oblique incident wave on two-dimensional periodic structures. By expressing the extra time derivatives caused by the field transformation technique as the form of the coefficient matrix, and adopting the LOD scheme… (More)
