In the last decade, metamaterials-based superlenses, with a resolution below Abbe's diffraction limit, have emerged. To obtain a rough estimate of the resolution of such superlenses, imaging of two subwavelength slits, separated by a subwavelength gap \textit{d} is typically performed. The resolution $\Delta$ of the lens corresponds to the minimum possible gap $d_{min}$ for which a distinct image of the two slits can be resolved ($\Delta \sim d_{min}$). In this letter, we present a more…

Super-resolution imaging using a three-dimensional metamaterials nanolens
Super-resolution imaging beyond Abbe’s diffraction limit can be achieved by utilizing an optical medium or “metamaterial” that can either amplify or transport the decaying near-field evanescent waves
Far-field optical superlens.
It is shown that a FSL can image a subwavelength object consisting of two 50 nm wide lines separated by 70 nm working at 377 nm wavelength and the optical FSL promises new potential for nanoscale imaging and lithography.
Near-Field Microscopy Through a SiC Superlens
This work combines the advantages of both techniques and demonstrates a novel imaging system where the objects no longer need to be in close proxim-ity to a near- field probe, allowing for optical near-field microscopy of subsurface objects at sub-wavelength-scale lateral resolution.
Negative refraction in semiconductor metamaterials.
A comparatively low-loss, three-dimensional, all-semiconductor metamaterial that exhibits negative refraction for all incidence angles in the long-wave infrared region and requires only an anisotropic dielectric function with a single resonance is demonstrated.
Imaging with subwavelength resolution by a generalized superlens at infrared wavelengths.
It is demonstrated that superlens imaging with subwavelength resolution well below Abbe's diffraction limit (0.5lambda2) can be achieved with photonic crystal structures nanofabricated in a InGaAsP/InP heterostructure platform.

This work describes planar subwavelength structures capable of focusing well beyond the diffraction limit, operating at arbitrary frequencies, and holds promise for near-field data storage, noncontact sensing, imaging, and nanolithography applications.

The authors' simulations show that a version of the lens operating at the frequency of visible light can be realized in the form of a thin slab of silver, which resolves objects only a few nanometers across.

Near‐field imaging by negative permittivity media
The imaging of the near field by a slab of negative permittivity medium is discussed. The performance of this flat lens is limited by the working wavenumber k0 and the slab thickness d. For k0d ≪
Plasmonics for near-field nano-imaging and superlensing
Diffraction of light prevents optical microscopes from having spatial resolution beyond a value comparable to the wavelength of the probing light. This essentially means that visible light cannot
