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…
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…
Coda reconstruction from cross-correlation of a diffuse field on thin elastic plates
Aida Hejazi Nooghabi, Lapo Boschi, Philippe Roux +1
This study contributes to the evaluation of the robustness and accuracy of Green's function reconstruction from cross-correlation of strongly dispersed reverberated signals, with d…
Enhanced sensing and conversion of ultrasonic Rayleigh waves by elastic metasurfaces
Andrea Colombi, Victoria Ageeva, Richard J. Smith +7
Recent years have heralded the introduction of metasurfaces that advantageously combine the vision of sub- wavelength wave manipulation, with the design, fabrication and size advan…
Reconstruction of Rayleigh-Lamb dispersion spectrum based on noise obtained from an air-jet forcing
Eric Larose, Philippe Roux, Michel Campillo
The time-domain cross-correlation of incoherent and random noise recorded by a series of passive sensors contains the impulse response of the medium between these sensors. By using…
