US Patent 11415556 Acoustic wave superscattering

A device can be configured to cause the superscattering of acoustic waves and/or to enable incident angle-dependent scattering. The acoustic superscattering device can include a body that has an outer peripheral surface. One or more resonators can be defined in the body. The one or more resonators can open to the outer peripheral surface of the body. When there are a plurality of resonators, the resonators are not in communication with each other within the body. The acoustic superscattering device can be configured to cause the superscattering of a target acoustic wave impinging upon the body.
