Normally, an object in thermal equilibrium with its environment emits and absorbs thermal radiation at the same rate (left). But researchers have developed a multilayer material (right) that, when ...

Prof Zhang Zhiyong's team at Peking University developed a heterojunction-gated field-effect transistor (HGFET) that achieves high sensitivity in short-wave infrared detection, with a recorded ...

With the rapid development of nanophotonics, spectrally selective infrared stealth technology has achieved great success through the design of metamaterials. However, as the background environment is ...

The observations are of fundamental importance for electrodynamics and will provide researchers with an entirely new method of absorbing the energy of electromagnetic waves MOSCOW, December 17. /TASS/ ...
