Scientists at the University of Michigan have developed a way to make a lens-like device that focuses electromagnetic waves down to the tiniest of points. The breakthrough opens the door to the next generation of technology, said Roberto Merlin, professor of physics at U-M. His research on the discovery will be published online July 12 in Science Express. Everywhere...
