Aerogel-based metasurfaces for perfect acoustic energy absorption
Antonio A. Fernández-Marín, Noé Jiménez, Jean-Philippe Groby +2
The unusual viscoelastic properties of silica aerogel plates are efficiently used to design subwavelength perfect sound absorbers. We theoretically, numerically and experimentally…
General method to retrieve all effective acoustic properties of fully-anisotropic fluid materials in three dimensional space
Arthur Terroir, Logan Schwan, Théo Cavalieri +3
Anisotropic fluid materials are of growing interest with the development of metamaterials and transformation acoustics. In the general three-dimensional case, such materials are ch…
Unidirectional zero sonic reflection in passive symmetric Willis media
Aurélien Merkel, Vicent Romero-García, Jean-Philippe Groby +2
In an effective medium description of acoustic metamaterials, the Willis coupling plays the same role as the bianisotropy in electromagnetism. Willis media can be described by a co…
Bright and Gap Solitons in Membrane-Type Acoustic Metamaterials
Jiangyi Zhang, Vicente Romero-García, Georgios Theocharis +3
We study analytically and numerically envelope solitons (bright and gap solitons) in a one-dimensional, nonlinear acoustic metamaterial, composed of an air-filled waveguide periodi…
