Subwavelength pulse focusing and perfect absorption in the Maxwell fisheye
Gautier Lefebvre, Marc Dubois, Younes Achaoui +4
Maxwell's fisheye is a paradigm for an absolute optical instrument with a refractive index deduced from the stereographic projection of a sphere on a plane. We investigate experime…
Quantum revival for elastic waves in thin plate
Marc Dubois, Gautier Lefebvre, Patrick Sebbah
Quantum revival is described as the time-periodic reconstruction of a wave packet initially localized in space and time. This effect is expected in finite-size systems which exhibi…
Unveiling Extreme Anisotropy in Elastic Structured Media
Gautier Lefebvre, Tryfon Antonakakis, Younes Achaoui +3
Periodic structures can be engineered to exhibit unique properties observed at symmetry points, such as zero group velocity, Dirac cones and saddle points; identifying these, and t…
One single static measurement predicts wave localization in complex structures
Gautier Lefebvre, Alexane Gondel, Marc Dubois +9
A recent theoretical breakthrough has brought a new tool, called \emph{localization landscape}, to predict the localization regions of vibration modes in complex or disordered syst…
Erosion dynamics of a wet granular medium
Gautier Lefebvre, Pierre Jop
Liquid may give strong cohesion properties to a granular medium, and confer a solid-like behavior. We study the erosion of a fixed circular aggregate of wet granular matter subject…
Experiments on Maxwell's Fish-eye dynamics in elastic plates
Gautier Lefebvre, Marc Dubois, Romain Beauvais +3
We experimentally demonstrate that a Duraluminium thin plate with a thickness profile varying radially in a piecewise constant fashion as h(r)=h(0)(1+(r/Rmax)), with h(0)=0.5 mm, h…
