This review serves as a comprehensive design strategy for designing quasi-zero stiffness
(QZS) mechanical metamaterials (MMs). It discusses their underlying deformation …

Aero-engine noise reduction has always been a critical challenge in the field of science and
engineering. Passive acoustic liners are considered one of the most effective structures for …

The sandwich structure composed of acoustic metamaterials and supports with superior
mechanical and acoustic properties has an extremely broad development prospect in …

This paper reports an experimental study on a cavity-type metamaterial for broadband
sound absorption to break the one-to-one correspondence between back cavity and …

The development of sound-absorbing metamaterials/metastructures provides a new way to
solve the problem of low-frequency and broadband sound absorption. However, designing …

Acoustic metamaterials (AMMs) are a form of man-made material that can be specifically
developed to have a sub-wavelength periodic structure with extraordinary characteristics not …

The imperative advance towards achieving “carbon neutrality” necessitates the development
of porous structures possessing dual acoustic and mechanical properties in order to mitigate …

This paper reports an experimental investigation of a phase-gradient acoustic metasurface
for duct acoustic applications, to evaluate the potential for attenuating acoustic modes and to …

Recent studies have demonstrated that granular aerogels with sub-50 μm particles surpass
conventional acoustic materials like glass fibers and polyurethane foams in low-frequency …

In this study, we design reconfigurable multi-phased negative Poisson's ratio metamaterial
(NPM) for low-frequency vibration reduction. The designed NPMs consist of a concave …
