Light scattering of periodic β-aligned carbon nanotubes -: art. no. 013902

We report interesting results of light scattering in periodic beta-aligned carbon nanotubes (CNTs). Observations of spatial symmetric scattering as a consequence of strong interference agree well with analysis of periodic hexagonal lattices of the CNTs. We found that the scattering is maximally enhanced at a particular angle where the backward incident and scattered directions are exactly superposed for both s and p polarization. The experimental results are explained using a mechanism of electromagnetically induced excitation of surface plasmon polaritons which result in enhanced backscattering effect in CNTs.
