Randy Atkins: Engineers like John Rogers, at the University of Illinois, are creating so-called metamaterials, structured to play tricks with light.

John Rogers: The hope is that you could engineer a material like that to bend light in such a way that it sort of moves around an object and creates a level of invisibility.

Randy Atkins: Until now, those structures have only been vanishingly small themselves. But Rogers has devised a way to print large sheets of a promising metamaterial.

John Rogers: So that you can create enough of it that you can begin to think about engineering applications of these structures.

Randy Atkins: Rogers says more work is needed for an invisibility cloak, but this new printing method may already allow advances in communication and imaging systems. With the National Academy of Engineering, Randy Atkins, WTOP News.
