Metamaterials could perform calculus with light waves

A properly structured material could convert a light wave to its derivative.

Our recently developed ability to structure materials at nanometer scales has led to a variety of applications, but few of them have made geeks as excited as they are about cloaking devices. Although still fairly limited, these cloaking devices rely on what are termed metamaterials—devices that are ...
