Acoustic density estimation of dense fish shoals
B. Tallon, P. Roux, G. Matte +2
Multiple scattering of acoustic waves offers a noninvasive method for density estimation of a dense shoal of fish where traditional techniques such as echo-counting or echo-integra…

Transformation seismology: composite soil lenses for steering surface elastic Rayleigh waves
A. Colombi, S. Guenneau, P. Roux +1
Metamaterials are artificially structured media that can focus (lensing) or reroute (cloaking) waves, and typically this is developed for electromagnetic waves at millimetric down…

Seismic metasurfaces: Sub-wavelength resonators and Rayleigh wave interaction
D. J. Colquitt, A. Colombi, R. V. Craster +2
We consider the canonical problem of an array of rods, which act as resonators, placed on an elastic substrate; the substrate being either a thin elastic plate or an elastic half-s…
