Electrons in graphene behave like light, only better

A team led by Cory Dean, assistant professor of physics at Columbia University, Avik Ghosh, professor of electrical and computer engineering at the University of Virginia, and James Hone, Wang Fong-Jen Professor of Mechanical ...

Engineering discovery brings invisibility closer to reality

Since the beginning of recorded time, humans have used materials found in nature to improve their lot. Since the turn of this century, scientists have studied metamaterials, artificial materials engineered to bend electromagnetic, ...

Ultrasounds dance the 'moonwalk' in new metamaterial

Metamaterials have extraordinary properties when it comes to diverting and controlling waves, especially sound and light: for instance, they can make an object invisible, or increase the resolving power of a lens. Now, researchers ...

Researchers peek at the forgotten component of light

(Phys.org) —Physicists from FOM institute AMOLF have for the first time simultaneously measured the electrical and magnetic fields of light. With such a measurement scientists can better understand the behaviour of light ...

Organic chemistry: Leading light waves astray

The development of structured synthetic materials with unusual electromagnetic properties, so-called metamaterials, promises to provide access to special physical effects of great technological interest. Metamaterials have ...
