2019 Light in Complex Materials WORKSHOP

Abstract: Recently we were able to deliver light energy to the objects embedded in a disordered medium by coupling incident light into time-resolved reflection eigenchannels that control the transmittance or reflectance due to the interference between waves experiencing multiple scattering in disordered media. It is well known that the long-range correlations between speckle patterns generated by multiple scattering represent the degree of the interference of the waves in mesoscopic physics. The correlations can therefore be an indicator of the maximal transmittance of the eigenchannels. However, the long-range correlations of the time-resolved speckle patterns have not been studied yet. In this study, we theoretically calculated the long-range correlations of the time-resolved speckle patterns and demonstrated numerical simulations to verify the results.
