Abstract :
An efficient finite-difference time- domain (FDTD) algorithm with a simple dispersive periodic boundary condition (DPBC) is developed to analyze dispersive periodic structures with skewed grids. The algorithm is easy to implement and is efficient in both memory usage and computational time. The validity of the approach is verified by comparing the results of a nanoplasmonic solar cell with results obtained from frequency domain solution and an axial FDTD/DPBC program.
