摘要：

Phononic crystals are acoustic metamaterials that are used to shape fluid droplets by controlling their interaction with acoustic waves in a manner tunable by the frequency of the excitation. By shaping the field generated by surface acoustic waves (SAWs), a precise control over the direction and the amplitude of the interfacial jetting of a sessile drop of liquid on non-piezoelectric materials is demonstrated.
