Plasmonic graded-index planar lens based on subwavelength features in the effective index regime


Journal Article

We experimentally demonstrate the planar focusing of Surface Plasmon Polaritons using space variant PMMA subwavelength features on top of a metallic film. Focusing is obtained by creating an effective graded refractive index profile. © OSA 2012.
