Growing Phenotype-controlled Phononic Materials from Plant Cells Scaffolds
Maroun Abi Ghanem, Liliane Khoryati, Reza Behrou +5
Biological composites offer self-healing properties, biocompatibility, high responsivity to external stimuli, and multifunctionality, due, in part, to their complex, hierarchical m…
Contact-based and spheroidal vibrational modes of a hexagonal monolayer of microspheres on a substrate
A. Vega-Flick, R. A. Duncan, S. P. Wallen +6
We study acoustic modes of a close-packed hexagonal lattice of spheres adhered to a substrate, propagating along a high-symmetry direction. The model, accounting for both normal an…
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…
Shear to longitudinal mode conversion via second harmonic generation in a two-dimensional microscale granular crystal
Samuel P. Wallen, Nicholas Boechler
Shear to longitudinal mode conversion via second harmonic generation is studied theoretically and computationally for plane waves in a two-dimensional, adhesive, hexagonally close-…
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…
