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 ...

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

A research team including members from the University of Michigan have unveiled a new observational technique that's ...

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

In part this is because the acoustic versions of metamaterials involve creating structures that have things like pendulums that oscillate in response to the sound wave. These structures work ...

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.

Steven Cummer: Now the field is, I think, much more focused on trying to find practical applications or practical devices that can be improved by using acoustic metamaterials. Janet Babin ...

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 ...

To work, the unit cell — the smallest component of the metamaterial — must be smaller than the acoustic wavelength in the study. “These materials sound like a totally abstract concept, but the math is ...

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 ...
