Caltech scientists build the world's first integrated terahertz scanners, the size of a fingertip. A new silicon microchip can do what no other silicon microchip could before, generating and transmitting radio waves in the terahertz range. The tiny chip operates at 300 times the speed of the CMOS chip in your smartphone, and could someday be used to peer through walls, inside containers and into the food supply. It can see a knife hidden inside a teddy bear, like the image above. It can even det...
