5 (a)–(d) x–z cross sections of the beam intensity are shown as a function of focal depth, zf, for a focused Gaussian beam propagating through in silico fractal medium 2. For each panel, the result for a single simulation is displayed on top, with the corresponding averaged result over N=100 randomly generated fractal media displayed on the bottom. For visualization, all images are self-normalized to a maximum value of 1.
