Abstract

This paper presents a parallel frequency-dependent finite-difference time-domain ((FD)²TD) method for plasma in the dispersive media. Results obtained with parallel and serial algorithms verify that parallel (FD)²TD has the same precision as the serial (FD)²TD, while the parallel approach could reduce the CPU time efficiently. A tunable filter is analyzed based on a one-dimensional photonic crystal containing a plasma defect by this method. The tunability of the photonic crystal filter can be achieved by adjusting the defect layer parameters instead of changing the dimension of photonic crystal.
