Scientists found a way to make sound travel in only one direction
This breakthrough could be translated to electromagnetic waves, with important implications for radar tech.
While these oscillations are usually a nuisance (and even dangerous when they cause vibrations in airplane engines), Noiray realized we could harness them for good: to make a one-way street for sound waves. Not only did the sound wave travel forward without reflecting backward, but it even emerged stronger than before, thanks to the energy boost from the circulator’s self-oscillations. Future communication systems, too, could benefit from this newfound ability to route signals without interference, guiding them efficiently along topological circuits.
