MWSW02 - Theory of wave scattering in complex and random media

In a first part, I will explain how correlations of the disorder can have a strong impact on light propagation in complex media. As an illustration, the particular case of a hyperuniform disorder will be discussed by showing its interest for the transparency of a medium or on the contrary allowing to maximize its absorption. In a second part, I will address the case of a disordered medium with a Chi2-type response and I will detail the subtle processes coming into play in this case.
