Nano-Scale Terahertz Antenna May Make Tricorders Real 185

MrSeb writes "Researchers from Imperial College London and A*STAR in Singapore have shown off a terahertz antenna that's just 100 nanometers across — about 30,000 times smaller than existing terahertz antennae — and two orders of magnitude stronger than other T-ray beam-forming techniques. T-rays are a lot like EHF (extremely high frequency), which is used by millimeter wave scanners in airports, medical imaging, and emerging wireless networking standards like WiGig — but stronger, faster, and more detailed. Where EHF radiation can see through your clothes, T-rays can penetrate a few millimeters of skin. Furthermore, because atoms and molecules have a unique terahertz-range signature, T-ray scanners can detect toxic substances, bombs, drugs — or even cancerous tumors under your skin. Most importantly, though, due to the nano scale of these antennae, it's possible to create huge antennae arrays on a single silicon chip, meaning hand-held T-ray scanners are now a possibility. In the not so distant future, every household might have a Star Trek-like tricorder capable of detecting cancer or other diseases."
