On the other hand, to understand the fine details of how THz interacts with matter, capturing what happens very close to the device’s surface—the “near-field phenomena”—is essential. Existing THz ...

A simple tweak to the usual setup is all that is needed to enhance a spectroscopy technique that uses terahertz wavelengths to probe samples, physicists at RIKEN University, Wakō, Japan, have ...

In a new study, researchers demonstrated long-term, non-invasive monitoring of blood sodium levels using a system that combines optoacoustic detection with terahertz spectroscopy. Accurate measurement ...

(a) A series of 15-THz beam profiles captured at various positions along the propagation when focused by a concave metallic mirror. The spot size is as small as 43 micrometers in a full width at half ...

Contrary to some theorists’ expectations, water does not form hydrogen bonds in its supercritical phase. This finding, which is based on terahertz spectroscopy measurements and simulations by ...

Researchers developed a low-cost, scalable terahertz amplifier that could be used to make antenna arrays that can steer and focus high-frequency terahertz waves, for applications like high-resolution ...

Glass-fiber-reinforced plastics (GFRPs) and renewable natural materials, such as wood and cork, are being used ever more widely in industrial lightweight construction. Damage invisible to the naked ...

The quest is on to make terahertz sources that are small, portable and capable of operating at room temperature. Such a breakthrough could lead to advances in everything from cancer screening to ...
