vertical dipole array structures, methods of producing vertical dipole array structures and forming large-area vertical nano-aperture arrays, photovoltaic devices and 2d and vertical dipole nano-aperture arrays

摘要

A vertical dipole array structure includes a substrate that supports a film, which is not comprised of a negative-index metamaterial. The film includes a plurality of tilt-oriented portions and apertures. At least two of the tilt-oriented portions are separated by an aperture, and the tilt-oriented portions are configured such that incident radiation is redirected into a negative or positive refraction direction.
