Experimental Evidence of Directivity-Enhancing Mechanisms in Nonlinear Lattices
R. Ganesh, Stefano Gonella
In this letter, we experimentally investigate the directional characteristics of propagating, finite-amplitude wave packets in lattice materials, with an emphasis on the functional…
Wave control through soft microstructural curling: bandgap shifting, reconfigurable anisotropy and switchable chirality
Paolo Celli, Stefano Gonella, Vahid Tajeddini +3
In this work, we discuss and numerically validate a strategy to attain reversible macroscopic changes in the wave propagation characteristics of cellular metamaterials with soft mi…
Nonlinear Waves in Lattice Materials: Adaptively Augmented Directivity and Functionality Enhancement by Modal Mixing
R. Ganesh, Stefano Gonella
The motive of this work is to understand the complex spatial characteristics of finite-amplitude elastic wave propagation in periodic structures and leverage the unique opportuniti…
Manipulating waves by distilling frequencies: a tunable shunt-enabled rainbow trap
Davide Cardella, Paolo Celli, Stefano Gonella
In this work, we propose and test a strategy for tunable, broadband wave attenuation in electromechanical waveguides with shunted piezoelectric inclusions. Our strategy is built up…
