Phys. Rev. Lett. 93, 013902 (2004) [4 pages]Light Scattering of Periodic β-Aligned Carbon NanotubesReceived 19 November 2003; published 2 July 2004 We report interesting results of light scattering in periodic β-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. © 2004 The American Physical Society URL:
