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…
