An Overview on Acoustic Metamaterials

2021
Acoustic metamaterials are artificially engineered composites composed of mesoscopic subwavelength units, which have recently become an active field with an enormous range of potential applications. These media, which derive their properties from their structure rather than from the chemical properties of their constitutive materials, can be tailored ...

Acoustic Metamaterials

MRS Bulletin, 2008
AbstractThe field of engineered materials with designed properties is expected to continue to grow in the future, and metamaterials are instrumental in allowing this freedom of design. Metamaterials, particularly acoustic, are still in the stage of infancy.

Metamaterials acoustic barrier

Applied Acoustics, 2021
Abstract Metamaterials represent a new technology in noise control fields. The first studies about metamaterials date back to the 1900s. The ability to deflect acoustic waves is due to the geometric of the structures that generate resonance effects, and to the periodic arrangement within the material.

The 2024 acoustic metamaterials roadmap [PDF]

Journal of Physics D: Applied Physics
Abstract Today, acoustic metamaterials (AMMs) form a core area of metamaterial research. They offer bespoke wave control, achievable through their rationally designed structure and are at the forefront of metamaterial applications and commercialisation.

'Maxwellian' macroscopic acoustics and acoustic metamaterials

The Journal of the Acoustical Society of America, 2008
For electromagnetic wave propagation it was found that there exist composite media exhibiting strong spatial dispersion. This has raised the question of the relevance of the spatial dispersion in the characterization of the new metamaterials. The present communication intends to show that exactly the same problematic occurs in acoustics when ...

A multilayered acoustic hyperlens with acoustic metamaterials

Applied Physics A, 2011
The acoustic hyperlens can be realized by an alternating layered structure of water and fluid with negative mass density. Based on this alternating layered principle, we propose that an acoustic metamaterial consisting of three layers in water background can be designed to replace the fluid with negative mass density.

New acoustics, based on metamaterial

The Journal of the Acoustical Society of America, 2012
With the capability to fabricate acoustical metamaterial:phononic crystals, double negative material and materials with material parameters based on the predetermined direction of sound propagation, one can control and manipulate sound propagation in solids and fluids.
