Abstract
A device for superscattering a target acoustic wave may include a body having an outer surface, at least one resonator being defined within the body and extending to an opening defined within the outer surface and configured to cause the superscattering of the target acoustic wave impinging upon the body, and a motor connected to the body and configured to selectively rotate the body.
Claims20
A device for superscattering a target acoustic wave comprising:
- a body having an outer surface;
- at least one resonator being defined within the body and extending to an opening defined within the outer surface, the at least one resonator being configured to cause the superscattering of the target acoustic wave impinging upon the body;
- and
- a motor connected to the body and configured to selectively rotate the body.
1 more element
A device for superscattering a target acoustic wave comprising:
- a body having an outer surface;
- a plurality of resonators being defined within the body and extending to an opening defined within the outer surface, the plurality of resonators being configured to cause the superscattering of the target acoustic wave impinging upon the body;
- a motor connected to the body and configured to selectively rotate the body;
- and
- wherein a superscattered cross-section of the target acoustic wave relative to a width of the body is approximately 4:1 when a rotation speed of the body is zero and changes as the rotation speed of the body changes.
