A research team at City University of Hong Kong (CityU) has discovered a new type of sound wave: the airborne sound wave vibrates transversely and carries both rotation and orbital angular momentum ...

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 ...

We are constantly dealing with waves that are deflected in complex ways: this could be a light beam passing through a glass of milk and being dispersed in all directions, or electromagnetic waves from ...

Metamaterials researchers have created a thin plastic structure with geometric details allowing it to control the redirection and reflection of sound waves with almost perfect efficiency.

NASA's Van Allen Probes have observed a new population of space sound waves, called plasmaspheric hiss, which are important in removing high-energy particles from around Earth that can damage ...
