Dynamic surface plasmon patterns generated by reconfigurable “cogwheel-shaped” beams
Z. J. Hu, X.-C. Yuan, S. W. Zhu, G. H. Yuan, P. S. Tan et al.
A method for generating and controlling dynamic surface plasmon patterns by highly focused cogwheel-shaped beams is studied theoretically and experimentally. The cogwheel beams are formed by collinear superposition of two LaguerreGaussian beams with equal but opposite topological charges. It is show ... [Appl. Phys. Lett. 93, 181102 (2008)] published Mon Nov 3, 2008.
