Subwavelength focusing using a negative-refractive-index transmission line lens

Abstract

We report simulations demonstrating subwavelength focusing of electromagnetic waves, from one homogeneous and isotropic dielectric to another, through a flat lens made of a realizable negative-refractive-index (NRI) metamaterial. The NRI metamaterial consists of a two-dimensional inductor/capacitor (L/C) loaded transmission line (TL) network in a dual (high… (More)
