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…
Acoustic flat lensing using an indefinite medium
M. Dubois, J. Perchoux, A. L. Vanel +10
Acoustic flat lensing is achieved here by tuning a phononic array to have indefinite medium behaviour in a narrow frequency spectral region along the acoustic branch. This is confi…
Low frequency acoustic stop bands in cubic arrays of thick spherical shells with holes
Guillaume Dupont, Alexander Movchan, Stefan Enoch +1
We analyse the propagation of pressure waves within a fluid filled with a three-dimensional array of rigid coated spheres (shells). We first draw band diagrams for corresponding Fl…
Clamped seismic metamaterials: Ultra-low broad frequency stop-bands
Y. Achaoui, T. Antonakakis, S. Brule +3
The regularity of earthquakes, their destructive power, and the nuisance of ground vibration in urban environments, all motivate designs of defence structures to lessen the impact…
Seismic waves damping with arrays of inertial resonators
Younes Achaoui, Bogdan Ungureanu, Stefan Enoch +2
We investigate the elastic stop band properties of a theoretical cubic array of iron spheres connected to a bulk of concrete via iron or rubber ligaments. Each sphere can move free…
