Mapping the resonance wavelengths of MWCNT as an optical nanoantenna
We investigated the surface plasmon resonances of multi-wall carbon nanotube (MWCNT) for applications as the optical antenna. We calculated the near-field and far-field response of MWCNT using finite integral technique. In addition, the effect of shape and dimensions on the optical response of MWCNT was studied. Also, the dielectric properties of MWCNT obtained from the experimental results in the literature were fitted with a DrudeLorentz model. Finally, a full mapping of the geometry (length and radius) dependence for MWCNT was presented and discussed.
