Abstract

Electromagnetic scattering theory and effective medium approach are applied to calculate effective permittivity of composite media comprising of single-walled carbon nanotubes (SWCNTs) in broad frequency range from radiofrequency to ultraviolet. We demonstrate theoretically the dominant role of finite length effect in the far-infrared conductivity spectra of SWCNT material due to the strong slowing down of surface polariton. The experimental evidence of the finite-length effect in the FIR spectra of SWCNT films is presented. Experimental results demonstrate the phenomena of localized plasmon resonance in SWCNTs and prove theoretically predicted antenna effect in SWCNTs in terahertz and far-infrared ranges.
