Nonreciprocal Willis coupling with active acoustic resonant metastructure for the directional manipulation of scattering waves

In this study, we first inversely derive the required Willis parameters for realizing the extreme contrast of scattering waves in the opposite direction. Then, we propose an active acoustic metastructure to achieve nonreciprocal Willis coupling and experimentally realize strong transmission and refl...
