Coupled Decorated Membrane Resonators with Large Willis Coupling

17 Mar 2019 Lau Joshua Tang Suet To Yang Min Yang Z.

We report the experimental studies on an acoustic scatterer consisting of a pair of coupled decorated membrane resonators (DMRs) that exhibits near extreme contrast in reflection asymmetry and strong Willis coupling coefficient with amplitude of 2.5 and polarizability cross term of 1.1 x 10-8 ms2. The design is based on the theoretical analysis using the Greens function formulism we developed earlier... (read more)
