| Popis: | 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. |
