title: Manipulating energy flow in variable-gap plasmonic waveguides.
abstract: We present an effective generic method for manipulating energy flow in a metal-dielectric-metal plasmonic waveguide by spatially varying the thickness of the dielectric layer. To illustrate the utility of our method, we theoretically design a plasmonic convex lens and analyze its performance using full-wave numerical simulations. In particular, we show that such a lens is low dispersive and broadband.
