Acoustic-electronic nonreciprocity through state- and dispersion-engineered systems
Abstract
Acoustic-electronic nonreciprocity through state- and dispersion-engineered systems. Time-reversal (T) symmetry is a fundamental characteristic of stationary media, but broken Tsymmetry is essential for unidirectional acoustic isolation, cloaking, and circulation. Till date, acoustic nonreciprocal systems remain far behind their electromagnetic counterparts. We propose a method to achieve linear time-invariant acoustic nonreciprocity using only reciprocal circuitacoustic and micromechanical components. The proposed work could enable control of acoustic reflections, improve sound-based imaging, and enable unidirectional acoustic cloaking.
