Longitudinal Eigenvibration of Multilayer Colloidal Crystals and the Effect of Nanoscale Contact Bridges
Maroun Abi Ghanem, Amey Khanolkar, Samuel P. Wallen +5
Longitudinal contact-based vibrations of colloidal crystals with a controlled layer thickness are studied. These crystals consist of 390 nm diameter polystyrene spheres arranged in…
Laser-Induced Spallation of Microsphere Monolayers
Morgan Hiraiwa, Melicent Stossel, Amey Khanolkar +2
The detachment of a semi-ordered monolayer of polystyrene microspheres adhered to an aluminum-coated glass substrate is studied using a laser-induced spallation technique. The micr…
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…
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…
