Characterization of Terahertz Frequency Scattering from Multi‐Walled Carbon Nanotube Arrays

Abstract

Carbon nanotube based physics is a relatively new field of study and electromagnetic characterization of oriented carbon nanotube materials is still in its infancy. We will present past and preliminary results of time domain terahertz spectroscopy measurements of scattering from vertically aligned arrays of multi- walled carbon nanotubes. Theoretical understanding of the observed phenomenon will be explored using results generated by Finite Element Method electromagnetics simulations. We will also discuss results from our more recent, ongoing experimentation efforts. The intent of this research is to both corroborate results from independent research groups conducting similar experiments and to further increase understanding in the scientific community with respect to carbon nanotube scattering phenomena.
