So-called "acoustic metamaterials" are specifically designed to control and manipulate sound waves, usually for the ... manipulation works in a different medium. “Rubber is hydrophobic, so ...

are also called capillary waves. Studied since antiquity, they have garnered considerable interest in modern science due to their ability to reveal information about the medium on which they travel.

2014 NOVA NextNOVA Next Using nothing more than waves, researchers were able to move this ping-pong ball around a tank of water. Share Once the figment of science fiction authors’ imaginations ...

The experiment looks like science fiction — or maybe even magic ... that demonstrate that they can use a 3-D-printed plate to manipulate sound waves into a complex "field" capable of creating ...

Singapore researchers say they have developed a way to tap the human body as a medium to draw energy and power wearables ... parasitic electromagnetic (EM) waves within a typical home or office ...

"This is the first confirmed evidence that black holes can exist in this medium-mass range." The idea of using gravitational waves to detect black holes is both very young and very old.

A fundamental manifestation of wave scattering in a disordered medium is the highly complex intensity pattern the waves acquire due to multi-path interference. Here we show that these intensity ...
