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 ...

Cover imageWith the aid of recently emerged metamaterials offering extraordinary properties unattainable in nature, ...

Scientists have, for the first time, directly observed phonon wave dynamics within self-assembling nanomaterials unlocking ...

Explore how metamaterials are revolutionizing architecture with acoustic invisibility, earthquake resilience, and energy harvesting solutions.

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 ...

The Physics of Sound: From Whale Songs to Invisibility Cloaks Blue whales communicate over 1,000 km via 188 dB songs (louder than a jet engine at 25m). Metamaterials bend sound waves around objects, ...

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 ...

"The multifunctionality of metamaterials—being simultaneously lightweight and strong while having tunable acoustic properties—make them great candidates for use in extreme-condition ...

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 ...
