Existence and characterization of edge states in an acoustic trimer Su-Schrieffer-Heeger model
I. Ioannou Sougleridis, A. Anastasiadis, O. Richoux +4
We report on a direct mapping of acoustic slender waveguides to the one dimensional trimer Su- Schrieffer-Heeger model, with neither chiral nor mirror symmetry. Importantly, we can…
Perfect absorption in mirror-symmetric acoustic metascreens
V. Romero-García, N. Jiménez, J. -P. Groby +5
Mirror-symmetric acoustic metascreens producing perfect absorption independently of the incidence side are theoretically and experimentally reported in this work. The mirror-symmet…
Stealth acoustic materials
V. Romero-García, N. Lamothe, G. Theocharis +2
We report the experimental design of a 1D stealth acoustic material, namely a material that suppresses the acoustic scattering for a given set of incident wave vectors. The materia…
Granular Graphene: direct observation of zigzag and armchair edge waves
Li-Yang Zheng, Florian Allein, Vincent Tournat +2
We propose a mechanical granular graphene obtained by replacing the carbon atoms with macroscopic spherical stainless steel beads in contact. The experimental measured dispersion r…
