Abstract: 

Light scattering and transport in disordered media has been extensively studied. On the fundamental side, the possibility to study coherent scattering (speckles) in optics has been an essential tool in mesoscopic physics. On the  applied  side,  methods  and  techniques  have  been  developed  for  sensing  and  imaging  in  complex  media.  New trends have emerged recently with the possibility to control light propagation using disordered materials.
In this talk we will review recent results in the theory of light transport (diffusion) and scattering (speckles) that predict unexpected behaviors of interest for the control of light matter-­-interaction.
We will discuss an invariance property of the average path length in a wave diffusion process [1], and the first measurement demonstrating this invariance [2].
In the study of speckle patterns, we will show that a spatial correlation between the reflected and transmitted intensities  persists  even  in  the  multiple  scattering  regime  [3].  This  makes  possible  to  quantify  the  level  of  information on a transmitted speckle that can be deduced from a measurement of the reflected part only. We will finally address the influence of correlations in the disorder on the scattering strength. In the case of hyperuniform materials (a specific class of correlated materials), we will show that disordered materials that are both dense and transparent can be designed [4].
I am indebted to O. Leseur, N. Fayard, A. Goetschy and R. Pierrat with whom most of this work was done.

CREOL Distinguished Seminar: "Time Reversal and Holography with Time Transformations" by Mathias Fink

Thursday, March 16, 2017 4:30 PM to 5:30 PM
HEC Room 125

 
Mathias FinkLangevin Institute

Abstract :

Because time and space play a similar role in wave propagation, wave control can be achieved or by manipulating spatial boundaries or by manipulating time boundaries. Here we emphasize the role of time boundaries manipulation. We show that sudden changes of the medium properties generate instant wave sources that emerge instantaneously from the entire wavefield and can be used to control wavefield and to revisit the holographic principles and the way to create time-reversed waves. Experimental demonstrations of this approach with water waves will be presented and the extension of this concept to acoustic and electromagnetic waves will be discussed.  More sophisticated time manipulations can also be studied in order to extend the concept of photonic crystals and wave localization in the time domain.
