Abstract :
Carbon nanotube films are characterized using Vector Network Analyzer (VNA) and Terahertz Time-Domain Spectroscopy (THz-TDS). Both transmission and reflection experiments are performed in order to measure the complex refractive index and the wave impedance. This method allows simultaneous extraction of both the permittivity and permeability without any assumptions. Experimental results are obtained from microwave to THz for various multi-walled and single-walled nanotube samples.
