Using terahertz time domain spectroscopy THz-TDS, THz transmission spectrum of the array with sub-wavelength apertures on the Nb thin film has been studied in the temperature range of 5—300 K. The extraordinary transmission is observed and the peak positions are in agreement with the computer simulation technology simulation results. The transmission amplitude increases with the decreasing temperature.
