The science of designing and engineering such materials is the subject of the field of metamaterials (Box 1), and the subset of this field, in which the aim is the control of acoustic waves ...

The Physics of Invisibility: Metamaterials and Cloaking Devices Metamaterials (negative refractive index) bend light around objects, creating "invisibility cloaks" (2006 Duke University breakthrough).

Acoustic and mechanical metamaterials can route and control sound with an unprecedented degree of control. We expect many more wonders, given the enormous opportunities that modern nanofabrication ...

So-called "acoustic metamaterials" are specifically designed to control and manipulate sound waves, usually for the purpose of dampening or transmitting sound. But such an acoustic device can only ...

On the other end, the tailor-made acoustic metamaterial was fastened into the opening. With the hit of the play button, the experimental loudspeaker set-up came oh-so-quietly to life in the lab.

Hong Kong-based Acoustic Metamaterials Group (AMG), a smart materials and acoustics firm, aims to expand the use of recycled plastic in the construction industry to help the sector lower its ...

On the other end, the tailor-made acoustic metamaterial was fastened into the opening. With the hit of the play button, the experimental loudspeaker set-up came oh-so-quietly to life in the lab.

Researchers from University of Wisconsin-Madison have unveiled a new acoustic metamaterial capable of moving and rotating ...

Acoustic metamaterials could be used in many applications. Large versions could be used to direct or focus sound to a particular location and form an audio hotspot. Much smaller versions could be used ...

A metamaterial with acoustic properties that can be reconfigured in less than one tenth of a second has been made by researchers at the University of Bristol in the UK. Created by Mihai Caleap and ...

Researchers at the universities of Sussex and Bristol in the UK are working towards making scenarios like these – and more – possible by employing "acoustic metamaterials" to manipulate sound ...
