  • Acoustic and elastic flatband formation in phononic crystals:methods and devices formed therefrom
    Patent number: 8875838
    Abstract: A phononic device is provided suitable for attenuating mechanical vibration, as well as acoustic vibration that propagate through a medium. Through the periodic inclusion of domains of a material in a matrix that vary in the ratio of the longitudinal speed of sound (CL) and the transverse speed of sound (CT) between the domains and the matrix of equal to or greater than 2.0 and 40, respectively; improved significant attenuation of vibration is achieved.
