Highly asymmetric interaction forces induced by acoustic waves in coupled plate structures

Mutual forces can be induced between coupled structures when the structures are stimulated by external acoustic waves. In this work, we propose a concept for asymmetric interaction between two coupled plate-like structures generated by plane waves that are incident in opposite directions. In additio...

Description
Summary:Mutual forces can be induced between coupled structures when the structures are stimulated by external acoustic waves. In this work, we propose a concept for asymmetric interaction between two coupled plate-like structures generated by plane waves that are incident in opposite directions. In addition to the striking contrast between the interaction strengths produced by the different incident waves, the mutual force induced by one of these incident pairs can be tuned extremely strongly because of the resonant excitation of the flexural plate modes. The highly asymmetric interaction with enhanced strength on a single side is potentially useful in applications such as the design of ultrasound instruments and sensors.
