The red central curve represents the theoretically optimal thickness \(t_{\textrm{opt}}\) in units of skin depth for space-filling sheets, calculated according to Eq. (8) and shown as a function of the skin-depth-to-gap-width ratio. The remaining two red curves correspond to \(\pm 3\)% departure from the maximal flux. The blue curve shows the average flux at \(t_{\textrm{opt}}\). Experimental data points are shown as correspondingly coloured dots; the experimentally optimal thicknesses are calculated using interpolation between the experimental data points; error bars correspond to 5% uncertainty.
