With a conventional lens sharpness of the image is always limited by the wavelength of light. An unconventional alternative to a lens, a slab of negative refractive index material, has the power to focus all Fourier components of a 2D image, even those that do not propagate in a radiative manner. Such "superlenses" can be realized in the microwave band with current technology. Our simulations show that a version of the lens operating at the frequency of visible light can be realized in the form…

Enhanced and tunable resolution from an imperfect negative refractive index lens

Material loss diminishes the ability of a negative refractive index material to function as a superresolution lens. We find that the transmittance of a negative index slab can be greatly enhanced at…
Aberration reduction and unique light focusing in a photonic crystal negative refractive lens.

Results prove the feasibility of an in-plane free space optical network based on negative refraction and two unique functions of this lens are demonstrated: refocusing outside of the PC and parallel focusing, enabling image transfer and real image formation, respectively.
Perfect cylindrical lenses.

Here it is shown how a hollow cylinder of material can be designed to magnify an image but otherwise with the same perfection as the original lens.
The problem of a perfect lens made of a slab with negative refraction

The problem of the principal existence of the perfect lens and superlensing is discussed. We have demonstrated that in the case of the virtual focus the idea of perfect lens based upon amplification…
Subwavelength imaging by a flat cylindrical lens using optimized negative refraction

We experimentally demonstrate subwavelength imaging by a “flat cylindrical” lens using negative refraction. A two-dimensional photonic crystal whose dispersion at the second band provides group…
Bringing the ‘perfect lens’ into focus by near-perfect compensation of losses without gain media

In this paper, the optical properties and imaging performance of a non-ideal Pendry’s negative index flat lens with a practical value for loss are studied. Analytical calculations of the optical…
Negative index of refraction, perfect lenses and transformation optics - some words of caution.

In this paper we show that a negative index of refraction is not a direct implication of transformation optics with orientation-reversing diffeomorphisms. Rather, a negative index appears due to a…
