    • openAccess   Analytical modeling of one-dimensional resonant asymmetric and reciprocal acoustic structures as Willis materials 

      Groby, Jean-Philippe; Malléjac, Matthieu; Merkel, Aurélien; Romero-García, Vicent; TOURNAT, Vincent; Torrent, Daniel; Li, Jensen IOP Publishing (2021-05-14)
      As building blocks of acoustic metamaterials, resonant scatterers have demonstrated their ability to modulate the effective fluid parameters, which subsequently possess extreme properties such as negative bulk modulus or ...

    • openAccess   Nonreciprocal and even Willis couplings in periodic thermoacoustic amplifiers 

      Olivier, Côme; Poignand, Gaëlle; Malléjac, Matthieu; Romero-García, Vicent; PENELET, guillaume; Merkel, Aurélien; Torrent, Daniel; Li, Jensen; Christensen, Johan; Groby, Jean-Philippe American Physical Society (2021-11-10)
      hermoacoustic amplifiers are analyzed in the framework of nonreciprocal Willis coupling. The closed form expressions of the effective properties are derived, showing that an applied temperature gradient causes the appearance ...
