Abstract:
Locally resonant acoustic metamaterials (LRM) are designed to inhibit wave propagation in targeted frequency bands, evoked by the resonant behavior of sub-structural elements attached to a host structure. Typically, the resonant attachments are periodically clustered on the host structure and scaled smaller than the wavelength of interest. A novel approach in designing LRM comprises 3D cellular structures. Such architectures exhibit diverse resonances that are tunable by modifying the geometry a...     »
