Using a phenomenon called "negative light," scientists invisibly transferred data disguised as background thermal radiation.

A thermal metasurface is made of a single layer of nanostructured silicon (gray) on top of glass (blue) and a metal mirror (gold). The nanostructured surface is specifically tailored so that it ...

Researchers in Australia have developed a new way to send digital information that is almost impossible to detect. The ...

Thermal radiation: Usually it depens only on the temperature (coal on the left), But with topological tricks, it is possible to make a surface emit thermal radiation only at certain points, so that a ...

In highly demanding markets, solar radiation can be the difference between a successful arrival and a complex commercial ...

A team of scientists has solved a long-standing problem in thermal imaging, making it possible to capture clear images of objects through hot windows. A team of Rice University scientists has solved a ...

Space is tough on materials. Radiation, UV light, atomic oxygen and sharp temperature swings can degrade metals, polymers and coatings over time. This article looks at the current ways researchers are ...

A new method to measure the continuous spectrum of light is set to improve thermal imaging and infrared thermography. A new method to measure the continuous spectrum of light, developed in the lab of ...

A team of engineers and material scientists in the Paul M. Rady Department of Mechanical Engineering at CU Boulder has developed a new technology to turn thermal radiation into electricity in a way ...
