ACOUSTIC METAMATERIAL WITH SIMULTANEOUSLY NEGATIVE EFFECTIVE MASS DENSITY AND BULK MODULUS |
摘要 |
A device with simultaneous negative effective mass density and bulk modulus has at least one tubular section and front and back membranes sealing the tubular section. The front and back membranes sealing the tubular sections seal the tubular section sufficiently to establish a sealed or restricted enclosed fluid space defined by the tubular section and the membranes, and restrict escape or intake of fluid resulting from acoustic vibrations. A pair of platelets are mounted to the membranes, with the individual platelets substantially centered on respective ones of the front and back membranes. |
