| contents | Nonreciprocity is most commonly associated with a large difference in the transmitted energy when the locations of the source and receiver are interchanged. This energy bias is accompanied by a difference in the transmitted phase. We highlight the role of this phase bias in breaking reciprocity in the steady-state vibration transmission characteristics of coupled nonlinear systems to external harmonic excitation. We show that breaking of reciprocity is most commonly accompanied by a simultaneous bias in the transmitted energy and phase. Energy bias alone, without any contribution from phase, can still lead to nonreciprocity, but only at very finely tuned system parameters. We provide a methodology for realizing response regimes of phase-preserving nonreciprocity using two independent symmetry-breaking parameters in the system. Our findings highlight the key contribution of phase in nonlinear nonreciprocity. |
