Researchers at MIT have built a small chip that can generate terahertz waves more effectively and more affordably than what’s currently out there. That’s huge, ‘cause terahertz waves sit between radio and infrared on the electromagnetic spectrum, so they can carry more data than radio waves and see through more materials than infrared light. This makes them a promising candidate for faster wireless communication, sharper medical imaging, better security scanners, and smarter environmental monitoring.
