DOI: 10.1038/nphys4036
Abstract: Controlled wave propagation in disordered media is a challenge because of scattering processes. Now it is shown that for speckled targets much larger than the wavelength, long-range correlations between the speckles enhance wave propagation control. read more here.

DOI: 10.1063/5.0061802
Abstract: Anisotropic photonic structures play a vital role in tailoring micro- and nanoscale light-matter interactions. In this work, we investigate the interference and localization effects in two-dimensional disordered media containing dipolar scatterers with anisotropic positional correlations.… read more here.

DOI: 10.1063/5.0147691
Abstract: Scattering through a natural porous formation (by far the most ubiquitous example of disordered medium) represents a formidable tool to identify effective flow and transport properties. In particular, we are interested here in the scattering… read more here.

DOI: 10.1103/physreve.97.052146
Abstract: We elucidate the impact of diffusive motion on the nature of anomalous dispersion in layered and fibrous disordered media. We consider two types of disorder characterized by quenched random velocities and quenched random retardation properties.… read more here.

DOI: 10.1103/physreve.97.062133
Abstract: The conventional theory of combustion describes systems where all of the parameters are spatially homogeneous. On the other hand, combustion in disordered explosives has long been known to occur after local regions of the material,… read more here.

DOI: 10.1103/physrevlett.119.033903
Abstract: We introduce a wave front shaping protocol for focusing inside disordered media based on a generalization of the established Wigner-Smith time-delay operator. The key ingredient for our approach is the scattering (or transmission) matrix of… read more here.

DOI: 10.1103/physrevlett.129.056001
Abstract: Time-resolved scattering experiments enable imaging of materials at the molecular scale with femtosecond time resolution. However, in disordered media they provide access to just one radial dimension thus limiting the study of orientational structure and… read more here.
