Abstract :
We performed time-domain terahertz (THz) spectroscopy on single-walled carbon nanotube films. We found that a filtration method provides an efficient way of fabricating thick nanotube films which is capable of effective shielding of THz waves. Shielding effectiveness of more than 40 has been achieved from our method. In addition, all of the films we fabricated demonstrate a good metallic behavior with a dispersion of optical constant relevant to simple Drude model.
