Seismic wave shield using cubic arrays of split-ball resonators
Bogdan Ungureanu, Younes Achaoui, Stephane Brule +3
Metre size inertial resonators located in the ground have been theoretically shown to interact with a seismic wave (attenuation, band gaps) to enable protection of surface structur…
The influence of building interactions on seismic and elastic surface waves
Bogdan Ungureanu, Sébastien Guenneau, Younes Achaoui +6
We outline some recent research advances on the control of elastic waves in thin and thick plates, that have occurred since the large scale experiment [Phys. Rev. Lett. 112, 133901…
Non-Euclidean elastodynamic cloaking theory and application to control of surface seismic waves with pillars atop a thick plate
Andre Diatta, Younes Achaoui, Sebastien Guenneau
In [AIP Advances 6, 121707 (2016)], a soil structured with concrete columns distributed within two specially designed seismic cloaks thanks to a combination of transformational ela…
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…
