Subwavelength focusing of light without evanescent waves by an array of nanoholes
We provide the first evidence of free-space subwavelength focusing without evanescent fields using a photonic nano-structure. Hot-spots smaller than half of the wavelength were observed at distances of tens of wavelengths from the structure.

Abstract

We provide the first evidence of free-space subwavelength focusing without evanescent fields using a photonic nano-structure. Hot-spots smaller than half of the wavelength were observed at distances of tens of wavelengths from the structure.
