Elastic wave propagation in solids can be controlled and manipulated by properly designed metamaterials. In particular, polarization conversion can be obtained by using anisotropic materials. In this paper, we propose a three-component locally resona

In this review, we present the results on sub-wavelength perfect acoustic absorption using acoustic metamaterials made of Helmholtz resonators with different setups. Low frequency perfect absorption requires to increase the number of states at low fr

The presented thesis discusses the numerical modeling of acoustic metamaterials for the design of lightweight components with improved vibroacoustic properties. Therefore, two different concepts of acoustic metamaterials are analyzed: Acoustic black

The objective of this doctoral thesis is to study three different innovative noise control techniques in ducts namely: acoustic metamaterials, porous absorbers and microperforates. There has been a lot of research done on all these three topics in th

Metamaterials are often defined as artificial compositions designed to exhibit desired physical properties. These materials attract a lot of research attention due to unusual behavior that may not yet have been seen in nature. Although there is no co

Stealth is a major issue in naval defence. In this context, DCNS Research wants to know if locally-resonant acoustic metamaterials represent a technological breakthrough in comparison to current anechoic materials. We propose here a design of structu
