Scientists use sound to control material behavior, could help devices adjust stiffness
Researchers have uncovered a way to control material behavior using sound. In a study ...
The interface between two facets of an artificial material known as a “Weyl phononic crystal” can not only negatively refract an airborne sound wave, it does so without reflecting it at all. This ...
