Topological Acoustic Sensing Using Nonseparable Superpositions of Acoustic Waves

Topological Acoustic Sensing Using Nonseparable Superpositions of Acoustic Waves

We introduce a method, topological acoustic sensing, which exploits changes in the geometric phase of nonseparable coherent superpositions of acoustic waves to sense mass defects in arrays of coupled acoustic waveguides. Theoretical models and experimental results shed light on the origin of the beh...
