Imaging the Near Field
S. Anantha Ramakrishna, J. B. Pendry, M. C. K Wiltshire +1
In an earlier paper we introduced the concept of the perfect lens which focuses both near and far electromagnetic fields, hence attaining perfect resolution. Here we consider refin…
Limitations on Sub-Diffraction Imaging with a Negative Refractive Index Slab
D. R. Smith, D. Schurig, Marshall Rosenbluth +3
Recently it has been proposed that a planar slab of material, for which both the permittivity and permeability have the values of -1, could bring not only the propagating fields as…
Optical gain removes absorption and increases resolution in a near-field lens
S. Anantha Ramakrishna, J. B. Pendry
A recent paper showed how to construct a lens that focuses near field radiation and hence produce resolution unlimited by wavelength. The prescription requires lossless materials w…
The asymmetric lossy near-perfect lens
S. Anantha Ramakrishna, J. B. Pendry, D. Schurig +2
We extend the ideas of the recently proposed perfect lens [J.B. Pendry, Phys. Rev. Lett. {\bf 85}, 3966 (2000)] to an alternative structure. We show that a slab of a medium with ne…
Comment on "Wave Refraction in Negative-Index Media: Always Positive and Very Inhomogeneous"
JB Pendry, D. R. Smith
In a recent Physical Review Letter [1] Valanju Walser and Valanju (VWV) called into question the basis of work on the so called negative index media (NIM). See for example [2,3]. T…
Comment on "Left-Handed Materials Do Not Make a Perfect Lens"
J. B. Pendry
In a recent Physical Review Letter [1] Garcia and Nieto Vesperinas (GNV) dispute the claim of perfect lensing made in [2]. The thrust of the GVN paper is that the solutions propose…
