Asymmetric frequency conversion with acoustic non-Hermitian space-time varying metamaterial
Xinhua Wen, Xinghong Zhu, Alvin Fan +5
Space-time modulated metamaterials support extraordinary rich applications, such as parametric amplification, frequency conversion and non-reciprocal transmission. However, experim…
Dirac cones and chiral selection of elastic waves in a soft strip
Maxime Lanoy, Fabrice Lemoult, Antonin Eddi +1
We study the propagation of in-plane elastic waves in a soft thin strip; a specific geometrical and mechanical hybrid framework which we expect to exhibit Dirac-like cone. We separ…
Structure-Composition Correspondence in Crystalline Metamaterials for Acoustic Valley-Hall Effect and Unidirectional Sound Guiding
Simon Yves, Geoffroy Lerosey. Fabrice Lemoult
Recently, the domain of topological insulators in condensed matter physics has been teeming with intriguing and very exciting discoveries. Notably, the capacity of guiding currents…
