Scientists have pioneered a new way to monitor sodium levels in the blood—without drawing a single drop. By combining terahertz radiation and optoacoustic detection, they created a non-invasive system ...

We propose and investigate a coherent terahertz scheme, which uses a free-electron beam to drive a set of closely patterned sub-wavelength holes. Each hole is an independent electromagnetic resonator ...

We present the study of a new structure for integrated rectifier, realized with standard CMOS technology, suitable to detect the terahertz radiation, at room temperature. The structure consists of a ...

Vanden Recycling has announced it is supporting research at Oxford University to develop terahertz spectroscopic imaging for ...

Terahertz radiation (THz), electromagnetic radiation with frequencies ranging between 0.1 and 10 THz, could be leveraged to ...

In a new study, researchers demonstrated long-term, non-invasive monitoring of blood sodium levels using a system that ...

Researchers developed an optoacoustic (OA) terahertz spectroscopy system that can be used for long-term, non-invasive monitoring of blood sodium levels. Their approach successfully reduces signal ...

With the United States joining Israel in its attacks on Iran's nuclear program, here is what we know about the radiation threat, and other health risks.
