Acoustic resonance coupling for directional wave control: from angle-dependent absorption to asymmetric transmission

We investigate acoustic wave coupling between two resonators of very different intrinsic losses, e.g. lossy and lossless resonators as an extreme case. We find that the resonator pair placed on a reflector exhibits angle-dependent absorption, showing an order of magnitude difference for opposite ang...
