Super-resolved imaging based on spatiotemporal wavefront shaping
Guillaume Noetinger, Samuel Métais, Geoffroy Lerosey +3
A novel approach to improving the performances of confocal scanning imaging is proposed. We experimentally demonstrate its feasibility using acoustic waves. It relies on a new way…
Three-dimensional acoustic lensing with a bubbly diamond metamaterial
Maxime Lanoy, Fabrice Lemoult, Geoffroy Lerosey +3
A sound wave travelling in water is scattered by a periodic assembly of air bubbles. The local structure matters even in the low frequency regime. If the bubbles are arranged in a…
Dirac cones and chiral selection of elastic waves in a soft strip
Maxime Lanoy, Fabrice Lemoult, Antonin Eddi +1
We study the propagation of in-plane elastic waves in a soft thin strip; a specific geometrical and mechanical hybrid framework which we expect to exhibit Dirac-like cone. We separ…
Structure-Composition Correspondence in Crystalline Metamaterials for Acoustic Valley-Hall Effect and Unidirectional Sound Guiding
Simon Yves, Geoffroy Lerosey. Fabrice Lemoult
Recently, the domain of topological insulators in condensed matter physics has been teeming with intriguing and very exciting discoveries. Notably, the capacity of guiding currents…
Multiple scattering enabled superdirectivity from a subwavelength ensemble of resonators
S. Metais, G. Lerosey, F. Lemoult
An ensemble of resonators arranged on a sub-wavelength scale is usually considered as a bulk effective medium, known as a metamaterial, and can offer unusual macroscopic properties…
Measuring Dirac Cones in a Sub-Wavelength Metamaterial
Simon Yves, Thomas Berthelot, Mathias Fink +2
The exciting discovery of bi-dimensional systems in condensed matter physics has triggered the search of their photonic analogues. In this letter, we describe a general scheme to r…
