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.
