Considerable research attention has been recently devoted to the study of periodic structures given their unique wave dispersion. Phononic crystals and acoustic metamaterials have emerged as two main categories of such periodic structures that can exhibit radically different band gap characteristics. Here, we present a novel configuration that combines hybrid wave attenuation attributes culminating in enhanced metadamping and energy dissipation properties. The results are compared with a benchmark example from literature to show the potential of the new design.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the conference proceedings. They include the speaker's narration along with a video recording of the presentation slides and animations. Many conference presentations also include full-text papers.
