Acoustic meta-atom with experimentally verified maximum Willis coupling

Willis coupling is an additional degree of freedom, which can enhance acoustic metamaterials, by coupling monopole and dipole excitations. Here, the authors experimentally demonstrate a meta-atom with Willis coupling approaching the theoretical maximum, which is robust to thermo-viscous losses.
