A presenter-led science video showing how to investigate infrared radiation, with Dr Maggie Aderin-Pocock and Dr Alex Lathbridge. The video investigates emissions of infrared radiation and then ...

Short-wave infrared radiation (SWIR) is roughly the part of the electromagnetic spectrum between 1.4 μm – 3 μm, or 100 THz – 214 THz. This places it between visible light and microwaves ...

In a joint experimental-theoretical work, a team of researchers, including theorists from UC San Diego, have shown for the ...

In physics, electromagnetic radiation (EMR) consists of waves of the electromagnetic (EM) field, propagating through space, carrying electromagnetic radiant energy. It includes radio waves, microwaves ...

Known as Sgr A* – pronounced “Sagittarius A star” – the supermassive black hole is four million times the mass of the sun and is known to exhibit flares that can be observed in multiple wavelengths, ...

Technology has now moved on, and it is now possible to generate continuous-wave terahertz radiation by exposing a semiconductor to beams from two infrared laser diodes that are very close in ...

The stronger waves are known for penetrating ... higher levels of infrared exposure — like those used in infrared saunas — may produce more radiation than lower doses, which can cause skin ...

such as infrared and UV waves. For example, mobile phones use microwave radiation for communication, and infrared cameras are utilized for night vision. Terahertz technology utilizes a type of ...

Prof Zhang Zhiyong's team at Peking University developed a heterojunction-gated field-effect transistor (HGFET) that achieves high sensitivity in short-wave ... weak infrared radiation at 0. ...

Highly sensitive shortwave infrared (SWIR) detectors are essential for detecting weak radiation (typically below 10 −8 W·Sr −1 ·cm −2 ·µm −1) with high-end passive image sensors ...
