Superlens - Wikipedia
A superlens is a lens which is capable of subwavelength imaging, allowing for magnification of near field rays. Conventional lenses have a resolution on the order of one wavelength due to the so-called diffraction limit.
Superlenses to overcome the diffraction limit - Nature Materials
Artificially engineered metamaterials now offer the possibility of building a superlens that overcomes this limit. We review the physics of such superlenses and the theoretical and experimental...
The Quest for the Superlens - Scientific American
Jul 1, 2006 · Built from "metamaterials" with bizarre, controversial optical properties, a superlens could produce images that include details finer than the wavelength of light that is used
Metamaterial Superlenses Operating at Visible Wavelength for …
Oct 31, 2018 · In this paper, a novel design for a metamaterial lens (superlens) based on a Photonic Crystal (PC) operating at visible wavelengths is reported. The proposed superlens consist of a gallium...
How to Build a Superlens | Science - AAAS
Apr 22, 2005 · One of the most dramatic—and controversial —predictions to emerge from this activity was a speculation by Pendry that a thin negative-index film should function as a “superlens,” providing image detail with a resolution beyond the diffraction limit to which all positive-index lenses are subject.
Hyperlenses and metalenses for far-field super-resolution imaging …
Nov 13, 2012 · Hyperlenses project super-resolution information to the far field through a magnification mechanism, whereas metalenses not only super-resolve subwavelength details but also enable optical...
Sub-Diffraction-Limited Optical Imaging with a Silver Superlens
Apr 22, 2005 · Recent theory has predicted a superlens that is capable of producing sub–diffraction-limited images. This superlens would allow the recovery of evanescent waves in an image via the excitation of surface plasmons.
A Local Superlens | ACS Photonics - ACS Publications
Here we demonstrate that a dielectric lamella of subwavelength size in all three spatial dimensions behaves as a compact superlens that operates at infrared wavelengths and can be positioned to image any local microscopic area of interest on the sample.
Spider Silk: Mother Nature’s Bio-Superlens | Nano Letters
Aug 17, 2016 · Here, we report for the first time a biological superlens provided by nature: the minor ampullate spider silk spun from the Nephila spider. This natural biosuperlens can distinctly resolve 100 nm features under a conventional white-light microscope with peak wavelength at 600 nm, attaining a resolution of λ/6 that is well beyond the classical ...
Overcoming losses in superlenses with synthetic waves of complex ...
Aug 17, 2023 · Superlenses made of plasmonic materials and metamaterials can image features at the subdiffraction scale. However, intrinsic losses impose a serious restriction on imaging resolution, a problem that has hindered widespread applications of superlenses.
