Wavenumber-space band clipping in nonlinear periodic structures
Weijian Jiao, Stefano Gonella
In weakly nonlinear systems, the main effect of cubic nonlinearity on wave propagation is an amplitude-dependent correction of the dispersion relation. This phenomenon can manifest…
Nonlinear harmonic generation in two-dimensional lattices of repulsive magnets
Weijian Jiao, Stefano Gonella
In this Letter, we provide experimental evidence of nonlinear wave propagation in a triangular lattice of repulsive magnets supported by an elastic foundation of thin pillars and w…
Doubly-nonlinear waveguides with self-switching functionality selection capabilities
Weijian Jiao, Stefano Gonella
In this article, we investigate the effects of the interplay between quadratic and cubic nonlinearities on the propagation of elastic waves in periodic waveguides. Through this fra…
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…
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…
