Interferometric experiments on the transmission matrix of diffusive neutral inclusions

By using tailored disorder in the regime of diffusive light propagation, core-shell cloaking structures have previously been presented. These make cloak and an arbitrary interior nearly indistinguishable from surrounding. This statement holds true for all incident polarizations light, a broad range directions three dimensions, visible wavelengths. Here, by performing interferometric transmission-matrix experiments, we investigate statistical wave properties miniaturized versions such structures. singular-value decomposition, derive eigenchannels eigenvalues to assess degree correlation among multiply scattered waves. We find small but significant differences eigenvalue distributions, suggesting that is lower neutral inclusion than homogeneously disordered reference sample, which corresponds surrounding inclusion. Likewise, similar between optically inspecting its spatial neighborhood. allow us reveal due different statistics underlying random walks light.
