Acoustic Metamaterial Wizardry
2020Acoustic metamaterials are non-naturally occurring structures consisting of arrays of sub-wavelength resonators designed to manipulate the propagation of sound, exhibiting effective negative density or modulus [1,2]. Counterintuitive metamaterial properties such as acoustic negative refraction, superlensing and cloaking have been demonstrated. Another

Acoustic Metamaterials at the Microscale
2023Micro-architected materials allow for tunability of extreme static mechanical properties such as stiffness, Poisson’s ratio, or strength. However, dynamic and acoustic properties of micro-architected materials remain largely unexplored, partially because it is challenging to measure their response at these scales.
