Multisector parabolic-equation approach to compute acoustic scattering by noncanonically shaped impenetrable objects
Adith Ramamurti, David C. Calvo
A lesser-known but powerful application of parabolic equation methods is to the target scattering problem. In this paper, we use noncanonically shaped objects to establish the limi…
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…
