3D finite-difference time-domain method (FDTD) is carried out to simulate femtosecond optical pulses incident on silver film perforated by subwavelength holes arrays. Both square arrays and hexagonal arrays of nanoholes in silver film are considered. It is found that optical transmittance of square arrays almost does not vary with the polarization direction of incident light, while optical transmittance of hexagonal arrays varies obviously, especially when the wavelength equals the periodicity of holes arrays. This will be important for applications of novel optical devices.
