Materials scientists aim to engineer intelligence into the fabric of materials or metamaterials for programmable functions. Engineering efforts can vary from passive to active forms to develop programmable metasurfaces using ...
Researchers at Duke University have demonstrated photodetectors that could span an unprecedented range of light frequencies by using on-chip spectral filters created by tailored electromagnetic materials. The combination ...
Tuning the instruments that produce some of our most indelible sound waves—guitars, pianos, vocal chords—has become commonplace, expected, easy.
Physicists and materials scientists have developed a compact optical device containing vertically stacked metasurfaces that can generate microscopic text and full-color holograms for encrypted data storage and color displays. ...
Metasurfaces are optically thin metamaterials that can control the wavefront of light completely, although they are primarily used to control the phase of light. In a new report, Adam C. Overvig and colleagues in the departments ...
The Internet of Things (IoT) and cyber physical systems have opened up possibilities for smart cities and smart homes, and are changing the way for people to live. In this smart era, it is increasingly demanded to remotely ...
For the first time, researchers have used ultra-thin layers of 2-D structures known as metasurfaces to create holograms that can measure the polarization of light. The new metasurface holograms could be used to create very ...
A team led by scientists at the University of Washington has designed and tested a 3-D-printed metamaterial that can manipulate light with nanoscale precision. As they report in a paper published Oct. 4 in the journal Science ...
AMOLF researchers and their collaborators from the Advanced Science Research Center (ASRC/CUNY) in New York have created a nanostructured surface capable of performing on-the-fly mathematical operations on an input image. ...
The signals from a lighthouse to ships at sea is an early example of optical communication, the use of light to transmit information. Today, researchers in the field of integrated photonics are using optical communications ...
