Abstract
A theoretical investigation for the conductivity of single walled
nanotube films is carried out with an effective medium model in
Terahertz region. The results are compared with the recent
experiment and a decrease of the real conductivity with increasing
frequency is predicted. Meanwhile, the off-diagonal components of
the dielectric function of single-walled carbon nanotube films
based on the magneto-optical effects are also shown.
