Elastic acoustic metamaterials
WebDec 1, 2014 · An acoustic metamaterial structure can attenuate/stop or guide an elastic wave propagating in it along a desired path by employing the resonance between the integrated local microstructures and the propagating wave. WebThis paper proposes an I-shaped radial elastic metamaterial with ultra-low-frequency broadband characteristics and studies the propagation characteristics of elastic waves in their quasi-static state. Through the calculation of the dispersion relationship, the frequency response function, and the eigenmode displacement field, it is found that the ultra-low …
