Tunable piezoelectric metamaterial for Lamb waves using periodic shunted circuits
David R. Schipf, Matthew D. Guild, Caleb F. Sieck
Piezoelectric elastic metamaterials offer the ability to overcome the fixed, narrow bandwidth characteristics of passive elastic metamaterials. Interesting ultrasonic band gaps exi…
Flexural wave modulation and mitigation in airfoils using acoustic black holes
Kaushik Sampath, Caleb F Sieck, Matthew D Guild +2
This study introduces a framework for the design and implementation of acoustic black holes (ABHs) in airfoils. A generalized multi-parameter damped-ABH generation function is mapp…
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…
