Effective Brownian diffusion coefficient of the bilayer phantoms. Error bars
represent standard deviations over 30 repetitions. Black lines represent the
values of DB in the two layers.
Fig8a: Measured DB of the phantom with 30% glycerol concentration in the upper
layer as a function of its thickness.
Fig8b: Measured DB of the different phantoms for an upper layer thickness
d = 10 mm.
