Abstract
A metamaterial (400) for attenuating acoustic transmission comprises a plurality of layers (410). Each layer (410) comprises a transmission structure (420) and a resonator (450), coupled to the transmission structure (420). The transmission structure (420) in a layer (410) is coupled to the transmission structures (420) of the layers (410) neighboring said layer (410). The resonator (450) in a layer (410) is coupled to the transmission structure (420) of the layers (410) neighboring said layer (410).
Claims15
A metamaterial for attenuating acoustic transmission, the metamaterial comprising a plurality of layers, each layer comprising:
- (a) a transmission structure, and
- (b) a resonator, coupled to the transmission structure,
- wherein the transmission structure in a layer is coupled by a coupling element to the transmission structures of the layer(s) neighboring said layer;
- wherein the resonator in a layer is coupled by a coupling element to the transmission structure of the layer(s) neighboring said layer.
