Surface Plasmon Excitation and Localization by Metal-Coated Axicon Prism
Micromachines, 2012 Collimated Gaussian beams are efficiently localized at the apex of a metal-coated axicon prism by surface plasmon excitations. We observed the light scattered at the apex and the light reflected by the prism. Intense scattered light was observed with the

Mimicking Localized Surface Plasmons with Structural Dispersion
Advanced Optical Materials, 2019 AbstractOne major obstacle in developing plasmonic devices is dissipative loss. Structural waveguide dispersion offers a route to tackle this problem. Although long range propagation of surface waves using this concept is recently reported, experimental realizations of localized surface plasmon resonances with suppressed dissipative loss still remain ...
