摘要： A superlens that includes, in one example embodiment, a positive-index material adjacent to a negative-index material, wherein the negative-index material includes aluminum. In a more specific embodiment, the positive-index material includes a dielectric layer, such as Poly(Methyl MethAcrylate) (PMMA), which is less than 50 nanometers thick. The negative-index material includes a smoothed aluminum layer less than 50 nanometers thick. The aluminum layer is disposed on the dielectric layer or vice versa, forming a superlens comprising the aluminum layer and the dielectric layer. In another embodiment, the superlens further includes plural aluminum layers separated by one or more layers of positive-index material. A mask is adjacent to the positive-index material. The mask may include one or more features that extend into a transparent substrate. The mask is positioned so that the positive-index material separates the mask from the smoothed aluminum layer. In an illustrative embodiment, the superlens is adapted for use with thermal lithography using nanoparticles.

摘要： An apparatus for creating a sub-wavelength image in the farfield. In an example embodiment, the apparatus includes a far-field superlens that is adapted to generate a sub-wavelength image or a sub-diffraction-limited image at a far field distance from a negative-index material included in the superlens. The example far-field superlens includes a positive-index material and an adjacent positive-index material. The negative-index material has an output aperture at a first surface. A second surface or interface is positioned at a far field distance from the negative-index material such that a cavity or gap is formed between the second surface and the first surface, wherein the second surface represents an imaging surface. The gap may be filled with a dielectric material or may include a vacuum or air. In a more specific embodiment, the superlens further includes a first mechanism for producing one or more sub-diffraction-limited beam features at a far field distance from the negative-index layer via the cavity in which propagating electromagnetic energy from the incident electromagnetic energy propagates.
