Mimicking Surface Plasmons with Structured Surfaces
JB Pendry, L Martin-Moreno, FJ Garcia-Vidal
Metals such as silver support surface plasmons: electromagnetic surface excitations localised near the surface which originate from the free electrons of the metal. Surface modes a…
Shearing the Vacuum - Quantum Friction
JB Pendry
We consider two perfectly smooth featureless surfaces at T=0, defined only by their respective dielectric functions, separated by a finite distance, and ask the question whether th…
Extremely Low Frequency Plasmons in Metallic Microstructures
JB Pendry, AJ Holden, WJ Stewart +1
The plasmon is a well established collective excitation of metals in the visible and near UV but at much lower frequencies dissipation destroys all trace of the plasmon and typical…
Negative Refraction Makes a Perfect Lens
JB Pendry
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,…
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…
Magnetism from Conductors, and Enhanced Non-Linear Phenomena
JB Pendry, AJ Holden, DJ Robbins +1
We show that microstructures built from non-magnetic conducting sheets exhibit an effective magnetic permeability, /mu_meff, which can be tuned to values not accessible in naturall…
