Research Progress and Development Trends of Acoustic Metamaterials [PDF]
Molecules, 2021 Acoustic metamaterials are materials with artificially designed structures, which have characteristics that surpass the behavior of natural materials, such as negative refraction, anomalous Doppler effect, plane focusing, etc.

Underwater acoustic metamaterials [PDF]
National Science Review, 2023 Abstract Acoustic metamaterials have been widely investigated over the past few decades and have realized acoustic parameters that are not achievable using conventional materials. After demonstrating that locally resonant acoustic metamaterials are capable of acting as subwavelength unit cells, researchers have evaluated the possibility ...

Sharkskin-Inspired Magnetoactive Reconfigurable Acoustic Metamaterials [PDF]
Research, 2020 Most of the existing acoustic metamaterials rely on architected structures with fixed configurations, and thus, their properties cannot be modulated once the structures are fabricated.

Ultra-low and ultra-broad-band nonlinear acoustic metamaterials [PDF]
Nature Communications, 2017 Linear acoustic metamaterials based on resonances are generally tunable but limited by their narrow bands. Here, Fang et al. fabricate one- and two-dimensional nonlinear acoustic metamaterials with a broadband, low-frequency, response—greatly suppressing

Bandwidth broadening in cavity-type sound-absorbing metamaterials via additional equivalent stiffness [PDF]
Scientific ReportsThe fixed acoustic characteristics of unit-cell cavities fundamentally limit the broadband sound absorption performance of cavity-type sound-absorbing metamaterials.

Journal of Applied Physics, 2021 Waves are generally characterized by angular frequency ω and wavevector k. Accordingly, this tutorial is structured into two parts, one on resonance-based acoustic metamaterials, in the frequency domain, and one on topological acoustics, based on the wavevector domain as topological structures inherently involve spatial configurations that are a step ...

Research Progress of Locally Resonance Acoustic Metamaterials [PDF]
E3S Web of Conferences, 2021 Bragg scattering phonon crystal and locally resonant acoustic metamaterials were introduced. In order to generate noise reduction, the lattice constant of Bragg scattering phonon crystal should be of the same order of magnitude as the wave length of the ...
