Controlling surface acoustic waves (SAWs) via temporally graded metasurfaces
Jonatha Santini, Xingbo Pu, Antonio Palermo +2
In this manuscript, the temporal rainbow effect for surface acoustic waves (SAW) is illustrated through a temporal analog of space metagradings. We show that a time-modulated array…
A Nonlinear Damped Metamaterial: Wideband Attenuation with Nonlinear Bandgap and Modal Dissipation
Bao Zhao, Henrik R. Thomsen, Xingbo Pu +6
In this paper, we incorporate the effect of nonlinear damping with the concept of locally resonant metamaterials to enable vibration attenuation beyond the conventional bandgap ran…
A multiple scattering formulation for elastic wave propagation in space-time modulated metamaterials
Xingbo Pu, Alessandro Marzani, Antonio Palermo
Space-time modulation of material parameters offers new possibilities for manipulating elastic wave propagation by exploiting time-reversal symmetry breaking. Here we propose and v…
Topological edge states of quasiperiodic elastic metasurfaces
Xingbo Pu, Antonio Palermo, Alessandro Marzani
In this work, we investigate the dynamic behavior and the topological properties of quasiperiodic elastic metasurfaces, namely arrays of mechanical oscillators arranged over the fr…
A multiple scattering formulation for finite-size flexural metasurfaces
Xingbo Pu, Antonio Palermo, Alessandro Marzani
We provide an analytical formulation to model the propagation of elastic waves in a homogeneous half-space supporting an array of thin plates. The technique provides the displaceme…
Lamb's problem for a half-space coupled to a generic distribution of oscillators at the surface
Xingbo Pu, Antonio Palermo, Alessandro Marzani
We propose an analytical framework to model the effect of single and multiple mechanical surface oscillators on the dynamics of vertically polarized elastic waves propagating in a…
