A camera for single pixel acoustic compressive sensing in air
Jeffrey S. Rogers, Charles A. Rohde, Matthew D. Guild +3
Acoustic imaging typically relies on large sensor arrays that can be electronically complex and often have large data storage requirements to process element level data. Recently,…
Superresolution through the topological shaping of sound with an acoustic vortex wave antenna
Matthew D. Guild, Christina J. Naify, Theodore P. Martin +2
In this paper, we demonstrate far-field acoustic superresolution using shaped acoustic vortices. Compared with previously proposed near-field methods of acoustic superresolution, i…
Generation of topologically diverse acoustic vortex beams using a compact metamaterial aperture
Christina J. Naify, Charles A Rohde, Theodore P. Martin +3
Vortex waves, which carry orbital angular momentum, have found use in a range of fields from quantum communications to particle manipulation. Due to their widespread influence, sig…
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…
