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…
Attenuation of surface modes in granular media
R. Zaccherini, A. Palermo, A. Marzani +3
In this work, an unconsolidated granular medium, made of silica microbeads, is experimentally tested in a laboratory setting. The objective is to investigate the attenuation mechan…
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…
Cloaking strategy for Love waves
Z. Chatzopoulos, A. Palermo, S. Guenneau +1
Love waves are antiplane elastic waves which propagate along the surface of a heterogeneous medium. Under time-harmonic regime, they are governed by a scalar equation of the Helmho…
Mitigation of Rayleigh-like waves in granular media via multi-layer resonant metabarriers
Rachele Zaccherini, Antonio Palermo, Alessandro Marzani +3
In this work, we experimentally and numerically investigate the propagation and attenuation of vertically polarized surface waves in an unconsolidated granular medium equipped with…
Rayleigh wave propagation in nonlinear metasurfaces
Antonio Palermo, Behrooz Yousefzadeh, Chiara Daraio +1
We investigate the propagation of Rayleigh waves in a half-space coupled to a nonlinear metasurface. The metasurface consists of an array of nonlinear oscillators attached to the f…
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…
Surface wave non-reciprocity via time-modulated metamaterials
Antonio Palermo, Paolo Celli, Behrooz Yousefzadeh +2
We investigate how Rayleigh waves interact with modulated resonators located on the free surface of a semi-infinite elastic medium. We begin by studying the dynamics of a single re…
Locally resonant metasurfaces for shear waves in granular media
Rachele Zaccherini, Andrea Colombi, Antonio Palermo +5
In this article the physics of horizontally polarized shear waves travelling across a locally resonant metasurface in an unconsolidated granular medium is experimentally and numeri…
