  • - Development of efficient numerical algorithms that compute the matrices mentioned above for 2D and 3D resonant materials made of electro-magnetic dipoles or Mie-type resonators, both for scalar and vector waves. - Elaborate an analytical model or the main statistical features of these matrices, by using tools of random matrix theory.

    With the recent development of wavefront shaping techniques for light waves, a large variety of coherent effects in disordered systems has been demonstrated and exploited. The goal of the project is to push forward this evolution by providing a theory for the scattering matrix of strongly scattering media made of resonant units. Although resonant materials are nowadays at the heart of atomic and molecular physics and nanophotonics, they have not been considered in wavefront shaping protocols so far. We propose to study the statistical properties of various operators built from the scattering matrix, which characterize both stationary and dynamical transport features. This includes the reflection and transmission matrices on the one hand, and the delay-time (also called Wigner-Smith) matrix and dwell-time matrix on the other. By means of numerical and analytical methods, we aim at taking advantage of the interplay between scattering and internal resonances to identify states and protocols useful for imaging, energy delivery, light confinement, or information processing.

    The successful candidate will be integrated to the team “Wave theory and mesoscopic physics” of the Langevin Institute (https ://www. institut- langevin.espci.fr/wavestheoryandmesoscopicphysics).
