Janus acoustic metascreen with nonreciprocal and reconfigurable phase modulations
Here, the authors introduce the concept of Janus acoustic metascreen for independent wavefront manipulations for two opposite incidences. They use acoustic circulators with rotating inner cores to achieve high nonreciprocity, and demonstrate tunable combinations of wavefront manipulations.
