“…In artificial LRAM the limit frequencies of the band gap essentially depend on the frequency of the resonators and hence they can provide an effective attenuation of harmonic waves of relatively low frequency, e.g. in the range of some kHz, without requiring very large dimensions as it happens for phononic crystals (Wu et al, 2007;Croënne et al, 2011;Hussein et al, 2014;Miniaci et al, 2015;Ma and Sheng, 2016;D'Alessandro et al, 2016). This property can be exploited in different contexts ranging from seismic insulation (Miniaci et al, 2016) to impact absorbers in small cars (Comi and Driemeier, 2017).…”

Locally resonant acoustic metamaterials have recently attracted a great interest due to their dynamic behaviour, characterized by a band gap at relatively low frequencies. This paper provides a numerical study, by means of finite element modal analyses, of the dynamic properties of 1D mass-inmass and 2D cellular locally resonant metamaterials. The 2D metamaterial is constituted by a cellular metallic lattice, filled by a soft light material with heavy inclusions or resonators. The influence of material parameters and cell geometry on the band gap width and frequency level are explored. In addition to the usual square lattice we also consider a hexagonal one, which proves to be more efficient for wave filtering.

“…Furthermore, at this small scale, novel nanofabrication techniques deliver the tailoring possibilities required for graded devices (e.g., Alonso-Redondo et al, 2015;Rey et al, 2016). Among the possible resonant metasurface designs for elastic waves proposed in recent years (e.g., Baravelli and Ruzzene, 2013;Miniaci et al, 2015;Lee et al, 2016;Matlack et al, 2016;Galich et al, 2017;Tallarico et al, 2017), the one made of a cluster of rods (the resonators) (Pennec et al, 2008;Wu et al, 2008;Achaoui et al, 2011;Colombi et al, 2016c) on an elastic substrate has revealed superior characteristics and versatility of use in particular toward the fabrication of graded design. The physics of this metasurface is well described through a Fano-like resonance (Miroshnichenko et al, 2010).…”

Elastic Wave Control Beyond Band-Gaps: Shaping the Flow of Waves in Plates and Half-Spaces with Subwavelength Resonant Rods

In metamaterial science, local resonance and hybridization are key phenomena strongly influencing the dispersion properties; the metasurface discussed in this article created by a cluster of resonators, subwavelength rods, atop an elastic surface being an exemplar with these features. On this metasurface, band-gaps, slow or fast waves, negative refraction, and dynamic anisotropy can all be observed by exploring frequencies and wavenumbers from the Floquet-Bloch problem and by using the Brillouin zone. These extreme characteristics, when appropriately engineered, can be used to design and control the propagation of elastic waves along the metasurface. For the exemplar we consider, two parameters are easily tuned: rod height and cluster periodicity. The height is directly related to the band-gap frequency and, hence, to the slow and fast waves, while the periodicity is related to the appearance of dynamic anisotropy. Playing with these two parameters generates a gallery of metasurface designs to control the propagation of both flexural waves in plates and surface Rayleigh waves for half-spaces. Scalability with respect to the frequency and wavelength of the governing physical laws allows the application of these concepts in very different fields and over a wide range of lengthscales.
