Abstract
Disclosed are systems for directing flexural waves acting upon a structure. In one example, a system includes a beam and a pair of scatterers disposed on the beam and configured to induce a flexural wave on the beam when actuated at a frequency. The system is configured to direct a direction of travel of the flexural wave acting on the beam based on the width of the beam, the distance between the scatterers forming the pair of scatterers, and/or a phase difference between the actuation of the pair of scatterers.
Claims9
A system comprising:
- a beam;
- a pair of scatterers disposed on the beam and configured to induce a flexural wave on the beam when actuated at a frequency;
- wherein the system is configured to direct a direction of travel of the flexural wave acting on the beam based on at least one of a width of the beam, a distance between the scatterers forming the pair of scatterers, and a phase difference between an actuation of the pair of scatterers;
- and
- wherein the phase difference between the actuation of the pair of scatterers is such that one of the scatterers forming the pair of scatterers is actuated at a 90-degree phase difference from the other.
