Improvement of Sound Insulation Through Double-Panel Structure by Using Hybrid Local Resonator Array [PDF]
Archives of Acoustics, 2023 In this paper, we present one approach to improve the soundproofing performance of the double-panel structure (DPS) in the entire audible frequencies, in which two kinds of local resonances, the breathing-type resonance and the Helmholtz resonance, are ...

A Honeycomb Based Graded Metamaterial Muffler with Broadband Sound Attenuation and Load Bearing Performances [PDF]
Archives of Acoustics, 2022 A challenge for developing acoustic metamaterials (AMMs) is considering the application of broadband muffling and load bearing capacity simultaneously. In this paper, a honeycomb based graded AMM muffler is proposed, which can widen the attenuation band ...

Energy Localization through Locally Resonant Materials [PDF]
Materials, 2020 Among the attractive properties of metamaterials, the capability of focusing and localizing waves has recently attracted research interest to establish novel energy harvester configurations. In the same frame, in this work, we develop and optimize a system for concentrating mechanical energy carried by elastic anti-plane waves. The system, resembling a

On the Free Vibrations of Non-Classically Damped Locally Resonant Metamaterial Plates
Nanomaterials, 2022 In this paper, the focus is on the free vibrations of locally resonant metamaterial plates with viscously damped resonators. Upon formulating a dynamic-stiffness model where the resonators are represented via pertinent reaction forces depending on the ...

On Anomalous Localized Resonance for the Elastostatic System [PDF]
SIAM Journal on Mathematical Analysis, 2016 We consider the anomalous localized resonance due to a plasmonic structure for the elastostatic system in $\mathbb{R}^2$. The plasmonic structure takes a general core-shell-matrix form with the metamaterial located in the shell. If there is no core, we show that resonance occurs for a very broad class of sources.

Matryoshka locally resonant sonic crystal [PDF]
The Journal of the Acoustical Society of America, 2011 The results of numerical modeling of sonic crystals with resonant array elements are reported. The investigated resonant elements include plain slotted cylinders as well as their various combinations, in particular, Russian doll or Matryoshka configurations. The acoustic band structure and transmission characteristics of such systems have been computed
