Phase retrieval based on intensity-only spatiotemporal wavefront shaping
Luis Alberto Razo-López, Marc Guillon, Fabrice Lemoult +1
We introduce a phase retrieval method based on harmonic field representations generated by intensity-only spatiotemporal modulation. A periodic amplitude angular modulation encodes…
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…
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…
Crystalline metamaterials for topological properties at subwavelength scales
Simon Yves, Romain Fleury, Thomas Berthelot +3
The exciting discovery of topological condensed matter systems has lately triggered a search for their photonic analogs, motivated by the possibility of robust backscattering-immun…
Exploiting spatiotemporal degrees of freedom for far field subwavelength focusing using time reversal in fractals
Matthieu Dupré, Fabrice Lemoult, Mathias Fink +1
Materials which possess a high local density of states varying at a subwavelength scale theoretically permit to focus waves onto focal spots much smaller than the free space wavele…
