Researchers at AMOLF, in collaboration with partners from Germany, Switzerland, and Austria, have realized a new type of metamaterial through which sound waves flow in an unprecedented fashion. It ...

Settling a half century of debate, researchers have discovered that tiny linear defects can propagate through a material faster than sound waves do. These linear defects, or dislocations, are what ...

The top layer represents the location of the sound source and the path of sound propagation (A). The bottom layers represent convergence zones with different sound propagation paths (B-F). Sound waves ...

Engineers at UConn’s College of Engineering are unlocking new frontiers in wave control and energy localization Osama Bilal, director of the Wave Engineering Laboratory for Extreme and Intelligent ...

Illustration of an intense laser pulse hitting a diamond crystal from top right, driving elastic and plastic waves (curved lines) through the material. The laser pulse creates linear defects, known as ...
