Carbon nanotubes carry plasmonic signals in the terahertz range of the electromagnetic spectrum, but only if they’re metallic by nature or doped. In new research, the Rice University laboratory of physicist Junichiro Kono disproved previous theories that dominant terahertz response comes from narrow-gap semiconducting nanotubes.
An international team of researchers has found a new way to switch magnetism that is at least 1,000 times faster than currently used in magnetic memory technologies.
Smartphones could be equipped to see through solid objects, say Caltech electrical engineers, who have developed tiny, inexpensive terahertz imagers.
Researchers at UT Dallas have designed an imager chip that allows mobile phones to see through walls and other objects.
Star Trek-style Tricorder medical scanners are a step closer to reality, say scientists, following the discovery of a new way of creating electromagnetic Terahertz waves - as currently used in full-body security scanners.
MIT scientists have come a big step closer to creating an explosives scanner that's safer than X-ray scanning and can detect a wider range of substances.
