Negative refraction makes a perfect lens
نویسنده
چکیده
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 of a thin slab of silver. This optical version resolves objects only a few nanometers across.

Some Problems with Negative Refraction* by John Michael Williams P. O. Box 2697, Redwood City, CA 94064 [email protected] Abstract J. B. Pendry's "Negative Refraction Makes a Perfect Lens" is analyzed. It appears that several statements may be understood in terms of lens design but not in terms of fundamental behavior of light. In a recent Letter, "Negative Refraction Makes a Perfect Lens" (P...
متن کاملLorentz covariance of the canonical perfect lens
The electromagnetic properties of classical vacuum (i.e., empty space) are characterized by its permittivity ǫ0 = 8.854 × 10 −12 F m and permeability μ0 = 4π × 10 −7 H m. In contrast, anti–vacuum has permittivity −ǫ0 and permeability −μ0 [1]. The perfect lens, as conceptualized by Pendry [2], consists of a slab of anti–vacuum sandwiched by two slabs of vacuum. While this perfect lens is an idea...

A perfect lens with unlimited resolution has always posed a challenge to both theoretical and experimental physicists. Recent developments in optical metamaterials promise an attractive approach towards perfect lenses using negative refraction to overcome the diffraction limit, improving resolution. However, those artificially engineered metamaterials are usually accompanied by high losses from...
متن کامل1 S ep 2 00 8 Does negative refraction make a perfect lens ?
A discussion of a question, studied earlier by V.Veselago in 1967 and by J. Pendry in 2000, is given. The question is: can a slab of the material with negative refraction make a perfect lens? Pendry’s conclusion was: yes, it can. Our conclusion is: no, in practice it cannot, because of the fluctuations of the refraction coefficient of the slab. Resolution ability of linear isoplanatic optical i...
متن کاملOptical negative refraction by four-wave mixing in thin metallic nanostructures.
The law of refraction first derived by Snellius and later introduced as the Huygens-Fermat principle, states that the incidence and refracted angles of a light wave at the interface of two different materials are related to the ratio of the refractive indices in each medium. Whereas all natural materials have a positive refractive index and therefore exhibit refraction in the positive direction...
