Sandia creates 3-D metasurfaces with optical possibilities

Metamaterials don't exist in nature, but their ability to make ultra-thin lenses and ultra-efficient cell phone antennas, bend light to keep satellites cooler and let photovoltaics absorb more energy mean they offer a world ...

Electrical signals dictate optical properties

Researchers at the University of Southampton's Optoelectronics Research Centre (ORC) have created an artificial material, a metamaterial, with optical properties that can be controlled by electric signals.

Trapping tiny particles: A versatile tool for nanomanipulation

At just 1/1000th of a millimeter, nanoparticles are impossible to see with the naked eye. But, despite being small, they're extremely important in many ways. If scientists want to take a close look at DNA, proteins, or viruses, ...
