Paper Abstract

In this paper, we present experimentally the transmission properties of THz pulse through subwavelength planar fractal slits on the copper foil. The transmission measurement is carried out using THz time-domain spectroscopy. THz spectroscopy of these fractal slits shows the featured frequency selectivity. Multiple band gaps and pass bands for THz wave are observed. THz transmission under different polarization for a 7-level fractal pattern is analyzed. The transmission spectra with the different levels of fractal slits are compared and discussed. Polarization dependent THz transmission is attributed to the localized resonance induced by the fractal pattern.
