A team of Penn State researchers has designed and computationally tested a type of humanmade metamaterial capable for the first time of manipulating a variety of acoustic waves with one simple device.

The Korea Research Institute of Standards and Science has developed a detachable acoustic lens that allows for easy adjustment of the focal length in ultrasonic inspection equipment. Much like ...

Taking inspiration from a popular executive toy ("Newton's cradle"), researchers have built a device -- called a nonlinear acoustic lens -- that produces highly focused, high-amplitude acoustic ...

Acoustic lenses are remarkable devices that just got cooler. A recent presentation at SIGGRAPH 2019 showed that with the help of 3D printing, it is possible to build the acoustic equivalent of optical ...

Three-dimensional printed acoustic lenses that focus ultrasound beams to arbitrary shapes within the brain have been developed by researchers at the Technical University of Valencia. The lenses ...

In a cover article in The Journal of Applied Physics, a team of Penn State researchers has designed and computationally tested a type of manmade metamaterial capable for the first time of manipulating ...
