On the use of aerogel as a soft acoustic metamaterial for airborne sound
Matthew D. Guild, Victor M. García-Chocano, José Sánchez-Dehesa +3
Soft acoustic metamaterials utilizing mesoporous structures have recently been proposed as a novel means for tuning the overall effective properties of the metamaterial and providi…
Transparent gradient index lens for underwater sound based on phase advance
Theodore P. Martin, Christina J. Naify, Elizabeth A. Skerritt +6
Spatial gradients in refractive index have been used extensively in acoustic metamaterial applications to control wave propagation through phase delay. This study reports the desig…
Highly-anisotropic elements for acoustic pentamode applications
Christopher N. Layman, Christina J. Naify, Theodore P. Martin +2
Pentamode metamaterials are a class of acoustic metafluids that are characterized by a divergence free modified stress tensor. Such materials have an unconventional anisotropic sti…
Sonic Gradient Index Lens for Aqueous Applications
Theodore P. Martin, Michael Nicholas, Gregory J. Orris +3
We study the acoustic scattering properties of a phononic crystal designed to behave as a gradient index lens in water, both experimentally and theoretically. The gradient index le…
