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.

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.

Acoustic conjugate metamaterials

Physical Review B, 2019
Compared to metamaterials based on regulation of real material parameters, artificial materials designed by controlling complex parameters exhibit richer physics and different functions. In this work, we present acoustic conjugate metamaterials, which possess complex mass densities and bulk compressibilities with opposite phases, to manipulate acoustic

Acoustic Metamaterial Absorbers

2021
Porous and fibrous materials provide effective and broadband acoustic absorption at mid/high audible frequencies. However, these traditional treatments result in thick and heavy layers when designed for low frequency audible sound. To overcome these limitations, in the recent years metamaterials have been proposed as an alternative to design sub ...
