Valley Hall phases in Kagome lattices
Natalia Lera, Daniel Torrent, Pablo San-Jose +2
We report the finding of the analogous valley Hall effect in phononic systems arising from mirror symmetry breaking, in addition to spatial inversion symmetry breaking. We study to…
Ultrathin acoustic parity-time symmetric metasurface cloak
Hao-Xiang Li, Maria Rosendo-Lopez, Yi-Fan Zhu +5
Invisibility or unhearability cloaks have been made possible by using metamaterials making light or sound flow around obstacle without the trace of reflections or shadows. Metamate…
Topological Sound
Xiujuan Zhang, Meng Xiao, Ying Cheng +2
Recently, we witnessed a tremendous effort to conquer the realm of acoustics as a possible playground to test with sound waves topologically protected wave propagation. Acoustics d…
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…
