Dispersion in media containing resonant inclusions: where does it come from?
Fabrice Lemoult, Mathias Fink, Geoffroy Lerosey
We study the propagation of waves in a quasi 1D homogeneous host medium filled with various resonators. We first prove that a far field coupling between the elements explains its d…
Ultra small mode volume defect cavities in spatially ordered and disordered metamaterials
Nadège Kaina, Fabrice Lemoult, Mathias Fink +1
In this letter we study metamaterials made out of resonant electric wires arranged on a spatial scale much smaller than the free space wavelength and we show that they present a hy…
Exploiting the Time-Reversal Operator for Adaptive Optics, Selective Focusing and Scattering Pattern Analysis
Sébastien Michel Popoff, Alexandre Aubry, Geoffroy Lerosey +3
We report on the experimental measurement of the backscattering matrix of a weakly scattering medium in optics, composed of a few dispersed gold nanobeads. The DORT method (Decompo…
Controlling Light Through Optical Disordered Media : Transmission Matrix Approach
S. M. Popoff, G. Lerosey, M. Fink +2
We experimentally measure the monochromatic transmission matrix (TM) of an optical multiple scattering medium using a spatial light modulator together with a phase-shifting interfe…
