Negative refractive index и ложка дёгтя




Unnatural optics create precise photonic lens

WEST LAFAYETTE, Ind. — Optical experiments using arrays of nanowires are demonstrating that the concept of a negative refractive index could be realized in practical systems. The work, done at Purdue University, attempts to reproduce results s


"In 1968, Russian theorist Victor Veselago predicted that composite metamaterials might be engineered to have negative permeability and permittivity. Such materials, Veselago theorized, would interact with their environment in exactly the opposite way from natural materials."

"A transmission medium with a negative index of refractions would enable a flat planar lens to focus light to precisions that are smaller than the wavelength of the light itself. With tunable versions of such photonic materials now being rushed into prototypes by labs worldwide, it is conceivable that not only could a "perfect" lens be created but that known electron effects could be translated into photonic operations to create sensors that could detect a single molecule."

Да, похоже литография снова выкрутится от могилы :)

Принстон, Пурду.. едрёна вошь..

"Using these plasmonic nanomaterials, we hope to directly manipulate light, guide it around corners with no losses and basically do all the fundamental operations we do with electronic circuits today, but with photons instead," said Shalaev."
