Scientists have developed a microdroplet 3-D laser system in which laser light shines forth in all directions from dye molecules lodged within spherical drops of helical molecules dispersed in a ...
The negative refraction of electrons in graphene has been seen for the first time in experiments done by physicists in the US. The work represents an important advance in the fabrication of graphene ...
US researchers have found a simpler, cheaper and more reliable way to make metamaterials with a negative index of refraction. Negative-index metamaterials have hit the headlines this year because of ...
