Nanowire arrays could improve solar cells

Transparent electrodes are a critical component of solar cells and electronic displays. To collect electricity in a solar cell or inject electricity for a display, you need a conductive contact, like a metal, but you also ...

Researchers 3-D print metamaterials with novel optical properties

A team of engineers at Tufts University has developed a series of 3-D printed metamaterials with unique microwave or optical properties that go beyond what is possible using conventional optical or electronic materials. The ...

Mirage software automates design of optical metamaterials

Sandia National Laboratories has created the first inverse-design software for optical metamaterials—meaning users start by describing the result they want, and the software fills in the steps to get there. The modern design ...

Building blocks to create metamaterials

Engineers at Caltech and ETH Zürich in Switzerland have created a method to systematically design metamaterials using principles of quantum mechanics.

Researchers create ultrafast tunable semiconductor metamaterial

An international team of researchers from Moscow State University (Russia), Sandia National Laboratories (U.S.), and Friedrich-Schiller University (Germany) have devised an ultrafast tunable metamaterial based on gallium ...

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 ...

Metamaterials open up entirely new possibilities in optics

Researchers at Chalmers University of Technology have developed a method that enables them to manipulate light to follow any predetermined path along a surface. The innovation has now been described as one of the world's ...
