We demonstrate an effective approach of modifying the long-range spatial correlation for light propagating inside random photonic waveguides by varying the shape of the waveguide. The functional form of spatial correlation is no longer universal in the regime of diffusive transport and becomes shape dependent due to the nonlocal nature of wave propagation.(More)
Iron is a metal essential for cellular metabolism. However, excess iron available for reactions contributes to the formation of dangerous reactive oxygen species, such as the hydroxyl radical, via the Fenton reaction. Therefore, intracellular iron levels are tightly constrained by a control system of proteins. This paper contains a mathematical model, in(More)
The diffusive description of wave transport in random media has a long history [1]. This macroscopic approach describes the ensemble-averaged intensity of the wave on scales longer than the transport mean free path . As such, the diffusive description has a practical advantage compared to the direct solution of the wave equation for each statistical(More)
