The incident THz pulses with frequency from 0.1 to 2.7THz could be partly filtered, and the central peak was at ∼0.26. The high frequency signal could be observed to decrease, especially for the frequency above ∼1THz. Moreover, the transmission peak from small-size sample with less hole arrays shifts to high frequency at ∼0.53THz due to both the effects of boundary condition and insufficient periodical extension. Furthermore, finite element method with surface plasmon polariton theory is employed to analyze this extraordinary optical transmission and filter phenomena.
