Conductance as a function of the out-of-plane magnetic field for a transverse magnetic focusing device with injector and collector QPCs set 1500 nm apart, and both gate voltages set to a 30 mV and b 40 mV. Fermi energies were set to 7 meV. Disorder was implemented in the systems by applying onsite potentials chosen at random from a uniform distribution within the range \([-U/2,U/2]\). Solid lines show the mean values for 201 realisations of that particular disorder strength, and the corresponding shaded areas show the peak-to-peak variance
