Conductivity of Carbon Nanotube Layers at Low-Terahertz Frequencies

Wave propagation in a dielectric rod waveguide loaded with carbon nanotube (CNT) layers was studied experimentally at the wide frequency range of 75-320 GHz. Analytical calculations and computer modeling indicate that the measured losses at low-terahertz frequencies are due to conductivity of the CN...

Description
Summary:Wave propagation in a dielectric rod waveguide loaded with carbon nanotube (CNT) layers was studied experimentally at the wide frequency range of 75-320 GHz. Analytical calculations and computer modeling indicate that the measured losses at low-terahertz frequencies are due to conductivity of the CNT layer. The observed rapid decrease of the conductivity with increasing frequency is related to finite lengths of CNTs.
