    摘要: Materials and methods for fabricating and using negative index materials are disclosed. A negative index material comprises a three-dimensional volume including a bulk solution and a plurality of unit cells disposed in the bulk solution in a substantially random pattern. Each unit cell comprises a periodic hole array pattern on a substrate or a resonator formed on a first surface of a substrate, and a thin wire pattern formed on a second surface of the substrate. The combination of the unit cells in the bulk solution produces a negative effective permeability and a negative effective permittivity over a frequency band of interest for the three-dimensional volume. The negative index material may be used to focus radiation by directing an incident radiation at the negative index material and generating a focused radiation by a negative refraction of the incident radiation in the negative index material.

    摘要: A structure includes a film having a plurality of nanoapertures and a semiconductor layer in connection with the film. The nanoapertures are configured to allow the transmission of a predetermined subwavelength of light through the film via the plurality of nanoapertures. The semiconductor layer facilitates the modulation of the predetermined subwavelength of light transmitted through the film. The structure also includes a carrier generator for modulating the predetermined subwavelength of light by generating charge carriers.
