Magic material flips refractive index
An incredible characteristic of a radical new material has been verified by American
physicists. Sheldon Schultz and colleagues at the University of California at San
Diego have built a composite material that exploits a quirk in the fundamental rules
of optics - it has a negative refractive index (R A Shelby et al 2001 Science 292
77). The special structure could overcome the diffraction limit to make a perfect
lens - and revolutionise optoelectronics.

Snell's Law Reversed in 'Left-Handed' Composite Material
PHYSICISTS VERIFY REVERSAL OF SNELL'S LAW IN 'LEFT-HANDED' COMPOSITE MATERIAL
"We have demonstrated for the first time that metamaterials can be engineered to have specific
electromagnetic behaviors that are physically impossible for natural materials," said UCSD physicist David
Smith.

An array of tiny rings and wires is all that is needed, Philip

Lefty Materials
Scientists have found many ways to affect the passage of light through different materials, bringing us
such devices as the telescope and polarized sunglasses. Now, two physicicsts at U.C. San Diego have
developed a medium in which light behaves backwards. A ray of light consists of electric and magnetic
fields oscillating in concert. The orientation of the two fields determines the direction in which the
light travels„a relationship physicists call the "right hand rule." In a "left-handed" material, however,
the light moves backwards, and all kinds of strange effects arise. For example, light refracts in the
wrong direction; so if water were a left-handed material, and one were to dip a pencil in it, instead of
magnifying the pencil, the water would make it look smaller. Particularly remarkable is the fact that
this new material is made entirely of ordinary copper arranged in a carefully calibrated array of tiny
rings and wires. The researchers hope to find applications for their discovery in the
telecommunications industry.

Light runs backwards in time
The concept of a refractive index is familiar to every physicist: wine glasses
sparkle, deep pools appear shallow and camera lenses focus sharp images. As
every physics student knows, Snell's law relates the angles of incidence and
refraction in materials with different refractive indices. However, physicists at the
University of California at San Diego have now made a material with a negative
refractive index.
In the June issue of Physics World magazine, John Pendry from Imperial College in
London, explains how they made this unusual material and describes its various
properties.
