Figure 5. Transmission enhancement by the purification of reflection eigenchannels with low reflectance.
a, Total reflectance with the increase of the number of iterations (blue) and total transmittance (green) measured at the same time. b and c, Intensity images of the reflected wave before and after the purification process. d and e, Intensity images of the transmitted wave before and after the purification process. Scale bar, 10 μm. Color bar indicates intensity in arbitrary units.
