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…

Non-reciprocal wave phenomena in spring-mass chains with effective stiffness modulation induced by geometric nonlinearity
Samuel P. Wallen, Michael R. Haberman
Acoustic non-reciprocity has been shown to enable a plethora of effects analogous to phenomena seen in quantum physics and electromagnetics, such as immunity from back-scattering a…
