Metasurfaces: Tiny tech with big potential

Imagine manipulating light with ultra-thin, flat sheets instead of bulky lenses and mirrors. That's the promise of metasurfaces, a nanostructure technology that can twist and bend light in ways never before possible.

Illuminating the unavoidable imperfections of nanostructures

A new study by a collaborative team from the University of Twente and the e-Science Center in Amsterdam compares the transmission of light through a utopian model with a real 3D nanostructure. These nanostructures are integral ...

World's first micromachine twists 2D materials at will

Just a few years ago, researchers discovered that changing the angle between two layers of graphene, an atom-thick sheet of carbon, also changed the material's electronic and optical properties. They then learned that a "twist" ...
