Control of thermal radiation at high temperatures is vital for waste heat recovery and for high-efficiency thermophotovoltaic (TPV) conversion. Previously, structural resonances utilizing gratings, ...

A team of researchers, which includes the University of Southampton, have developed new technology which could prompt a significant change for a spacecraft or satellite. Metamaterial optical solar ...

Thermal cloaking advances stealth technology by using nanostructured materials to manipulate heat signatures, vital for military and electronic applications.

As the global energy crisis intensifies and climate change accelerates, finding sustainable solutions for energy management is increasingly urgent. One promising approach is passive radiative cooling, ...

If a material absorbs light, it will heat up. That heat must go somewhere, and the ability to control where and how much heat is emitted can protect or even hide such devices as satellites. An ...

Wavelength-selective thermal emitters (WS-TEs) have been frequently designed to achieve desired target emissivity spectra, as a typical emissivity engineering, for broad applications such as thermal ...

What does this mean to a firefighter using a TI outdoors? During initial size-up while conducting a 360° survey around a structure, we need to remember how a TI interprets images—e.g., white is hot, ...

FLIR Systems has published a new technical note that investigates and describes how to use low-cost materials to increase target emissivity to enable accurate measurement using a thermal imaging ...
