Plasmonics

Subwavelength imaging in colour

Nature Photonics volume 2, pages 387–388 (2008)Cite this article

A chain of nanorods with weakly damped plasmon resonances is able to perform far-field colour imaging with subwavelength resolution, according to theoretical simulations.

Much of the recent excitement in the field of metamaterials has focused on the development of perfect superlenses that are capable of imaging with subwavelength resolution1. The idea is to construct superlenses from metamaterials with a dielectric permittivity and a magnetic permeability that are both negative. This gives rise to a negative-refractive-index material and allows the evanescent light near the object to be captured and used to reconstruct a near-field image with subwavelength resolution.
