Creating ‘metamaterials’ with negative(-) refractive index

Filed under: Science — AjitK @ 10:39 am

The team of German scientist, lead by Gunnar Dolling at the University of Karlsruhe, has won the coveted race for creating materials with negative refractive index. The effect has been observed in a nanostructure (made from alternating layers of silver and magnesium fluoride on glass) at 780nm (far red end of the visible spectrum).
