Researchers at ETH Zurich have managed to make sound waves travel only in one direction. In the future, this method could also be used in technical applications with electromagnetic waves. Water, ...
DARPA is looking for a platform that can tell whether Internet of Things devices have been hijacked based on fluctuations in the heat, electromagnetic waves and sound they put out as well as the power ...
In the ETH experiment, self-oscillations (blue-red) cause sound waves (green, orange, violet) to travel through the circulator only in one direction. Credit: Xin Zou Researchers at ETH Zurich have ...
