Effects of the randomness of the central line beam positions on the transmission intensity. (a) Mean transmission spectra for the 5.3-mm-diameter beams in the central line and the different values of the disorder. (b) Normalized transmitted intensity versus amplitude of the disorder, as indicated. (c) same as Fig. 2b at 6195 Hz. (d, e) Intensity map at 6195 Hz for 2 mm and 5 mm random displacements of the beams in the central line. The intensity maps are normalized by the maximum transmitted intensity for the case without disorder. (c–e) The beam motion amplitude is depicted as a ‘log’ scale.
