Terahertz

Researchers have created a tiny chip that can take images of objects through cardboard. The technology, designed to fit inside a smartphone, brings us a step closer to wielding Superman’s X-ray vision abilities (without the X-rays).

Terahertz radiation is extremely useful but, traditionally, tricky and expensive to generate. Scientists at TU Wien have come up with a new source of terahertz radiation that they claim breaks records for efficiency and the breadth of its spectrum.

Researchers have developed a lens that operates at terahertz frequencies that are not only simple and inexpensive, but are claimed to produce near-flawless images which could vastly improve biomedical imaging as well as biological and explosive security scanning.

Researchers at MIT in the US and DESY (Deutsches Elektronen-Synchrotron) in Germany have developed a technology that uses high-frequency electromagnetic waves and could shrink particle accelerators by a factor of 100 or more.

A theoretically perfect optical absorber has been invented and demonstrated by researchers at Harvard University.

Terahertz sensing could allow for remote optical detection of hidden explosives, chemical weapons, biological agents or illegal drugs.
