Complex contact-based dynamics of microsphere monolayers revealed by resonant attenuation of surface acoustic waves
Morgan Hiraiwa, Maroun Abi Ghanem, Samuel P. Wallen +3
Contact-based vibrations play a critical role in the dynamics of granular materials. Significant insights into vibrational granular dynamics have been obtained with reduced-dimensi…
Dynamics of a Monolayer of Microspheres on an Elastic Substrate
Samuel P. Wallen, Alexei A. Maznev, Nicholas Boechler
We present a model for wave propagation in a monolayer of spheres on an elastic substrate. The model, which considers sagittally polarized waves, includes: horizontal, vertical, an…
A Self-Assembled Metamaterial for Lamb Waves
Amey Khanolkar, Samuel Wallen, Maroun Abi Ghanem +3
We report the design and characterization of a self-assembled, locally resonant acoustic metamaterial for Lamb waves, composed of a monolayer of m polystyrene microsphere…
