Plasmonic Nanostructures For Local Field Enhancement In The Uv Region

Keywords

Abstract

In this work we describe an ultraviolet subwavelength focusing in plasmonic nanostructures. A system which provides a 20-25 times local field enhancement at a wavelength of 350 nm is proposed. This system represents a metalized V-shaped groove in a surface of a dielectric medium. Subwavelength focusing is achieved by a plasmon wave propagation along the surface of metal film and by the transfer of electromagnetic field through the dielectric medium. The influence of system parameters on a local field enhancement is investigated. A simplified model that allows for determining the geometric parameters of an optimized resonator is proposed. © 2013 Elsevier B.V.
