Localized modes on a metasurface through multi-wave interactions
Martin Lott, Philippe Roux, Léonard Seydoux +4
In this paper, we describe the manifestation of localized states through coherent and incoherent analyses of a diffuse elastic wavefield inside a two-dimensional metamaterial made…
Tailored elastic surface to body wave Umklapp conversion
Gregory J. Chaplain, Jacopo M. De Ponti, Andrea Colombi +7
Elastic waves guided along surfaces dominate applications in geophysics, ultrasonic inspection, mechanical vibration, and surface acoustic wave devices; precise manipulation of sur…
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…
Mitigation of seismic waves: metabarriers and metafoundations bench tested
Andrea Colombi, Rachele Zaccherini, Antonio Palermo
The article analyses two potential metamaterial designs, the metafoundation and the metabarrier, capable to attenuate seismic waves on buildings or structural components in a frequ…
Graded metasurface for enhanced sensing and energy harvesting
Jacopo M. De Ponti, Andrea Colombi, Raffaele Ardito +3
In elastic wave systems, combining the powerful concepts of resonance and spatial grading within structured surface arrays enable resonant metasurfaces to exhibit broadband wave fo…
Elastic wave control beyond band-gaps: shaping the flow of waves in plates and half-spaces
Andrea Colombi, Richard Craster, Daniel Colquitt +4
It is well known in metamaterials that local resonance and hybridization phenomena dramatically influence the shape of dispersion curves; the metasurface created by a cluster of re…
