In this paper consistent bounds of the wave propagation properties concerning a Single Wall Carbon NanoTube (SWCNT) modeled as a Transmission Line are assessed. The monotonic inclusion property of the Interval Analysis leads to guaranteed limits for the given characteristics when the model parameters are uncertain. The common mode wave propagation in a SWCNT is considered and the variability range of the attenuation constant, the propagation velocity, the wavelength and the characteristic impedance in the frequency range up to 10 GHz due to physical and geometric uncertain parameters are evaluated. The obtained results are verified by means of a Monte Carlo analysis. The proposed approach furnishes a more reliable information than that derived from the classical sensitivity analysis. © 2008 IEEE.
