title: Surface plasmon converging and diverging properties modulated by polymer refractive structures on metal films.
abstract: Polymer refractive microstructures are fabricated on metallic thin films and employed to modulate surface plasmons (SPs) propagations in a refractive manner. SP waves converging with different focal lengths and diverging effects are realized by the refractive structures. Authors investigated the modulation effect on SP waves as a function of different thicknesses and different shapes of the polymer micro-structures based on the effective refractive index model, where imaging properties of the SPs are observed experimentally by detecting the leaky radiation intensity of the SPs.
