Chip-based system for terahertz waves could enable more efficient, sensitive electronics
88% Informative
Terahertz waves, which have shorter wavelengths and higher frequencies than radio waves, could enable faster data transmission, more precise medical imaging, and higher-resolution radar.
Current techniques can't generate waves with enough radiating power for useful applications unless they utilize bulky and expensive silicon lenses.
MIT researchers used Intel transistors to create a more efficient, yet scalable, chip-based wave generator.
This compact chip could be used for applications like improved security scanners for detecting hidden objects.
The researchers needed to devise a technique for installing the matching sheet that could be scaled up in a manufacturing facility.
Moving forward, they want to demonstrate this scalability by fabricating a phased array of CMOS terahertz sources.
They want to steer and focus a powerful beam with a low-cost, compact device.
