It is possible to make a material emit more radiation than it absorbs, violating the laws of physics in a way that could make ...

New results published in the journal Physical Review Letters detail how a specially designed metamaterial was able to tip the ...

A research team from Penn State has broken a 165-year-old law of thermal radiation with unprecedented strength, setting the ...

“Scientists have long observed that the capability for a material to absorb electromagnetic radiation — a wave of energy in the form of sunlight and X-rays, among others — at a given wavelength and ...

Houses coated with meta-emitters can reflect the sun's heat radiation and thus keep them passively cool. An AI determines ...

Thermal radiation, which originates from random fluctuations in materials, is traditionally considered an incoherent signal. Most conventional thermal emitters show weak to zero circular ...

WEST LAFAYETTE, Ind. – An international research team has used a "thermal metamaterial" to control the emission of radiation at high temperatures, an advance that could bring devices able to ...

Customised Thermal Radiation | TU WienUsually, thermal radiation depends only on the temperature, But a team of researchers found: with topological tricks, it is possible to make a surface emit ...

An international team of researchers, led by Drexel University, has found that a thin coating of MXene — a type of two-dimensional nanomaterial discovered and studied at Drexel for more than a decade ...
