Terahertz (THz) waves are located between microwaves and infrared light in the electromagnetic spectrum. They can pass through many materials without causing damage, making them useful for security ...

How could we noninvasively distinguish between healthy and cancerous tissue? And how could we increase the speed of wireless ...

(Phys.org)—By illuminating a thin film of water with ultrashort laser pulses, physicists have demonstrated that liquid water can generate terahertz (THz) waves, which are currently being researched ...

Terahertz (THz) waves, located between the millimeter and far-infrared frequency ranges, are an electromagnetic frequency band that is as-yet incompletely recognized and understood. Xiaojun Wu of ...

A team of engineers has developed a new type of camera that can detect radiation in terahertz (THz) wavelengths. This new imaging system can see through certain materials in high detail, which could ...

How researchers created metasurfaces for THz signal distribution that don't have the typical drawbacks of similar structures. How the tile arrays are laid out to form the metasurface. What do the meta ...

Photo of a supercontinuum being generated by a short-pulsed laser. The creation of a plasma produces light that spans the visible and invisible parts of the electromagnetic spectrum. The search for ...

Researchers showed that long-wavelength terahertz (THz) spectroscopy can detect motion of single molecules, not just molecular ensembles. They used a single-molecule transistor design, where pairs of ...

Liquid water sustains life on earth, but its physical properties remain mysterious among scientific researchers. Recently, a team of researchers used existing THz spectroscopy techniques to measure ...

I work in optics, so when I’m in grant-writing mode, optics and lasers seem to be the best technology choice for every problem, including powering coffee machines. But in the part of the multiverse ...
