Smart metamaterials that sense and reprogram themselves

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 ...

Light-trapping nanocubes drive inexpensive multispectral camera

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 ...

Researchers create better light-trapping devices

Anyone who's ever played the drums, tuned a guitar, or even made a wine glass "sing" by circling a finger along its edge knows about resonance. Acoustic resonators, like the cavity of a drum or a half-full wine glass, naturally ...

Physicists image electrons flowing like water for the first time

Physicists at the Weizmann Institute of Science in Israel have imaged electrons flowing viscously through a nanodevice, just like water flowing through a pipe. Long predicted but only now visualized for the first time, this ...
