Figure 4
Behavior of the OAM as a function of thickness z and convergence semi-angle α for an incident m = 1 vortex beam for three different samples. Left: Si₃N₄, center: Fe_0.8B_0.2, right: Pt. Top: OAM expectation value $[\langle\hat{L}_{z}\rangle]$ , middle: standard deviation of the OAM $[\sigma[\hat{L}_{z}]]$ , bottom: intensity of the m = 1 component. Note the different color bar ranges. All data were averaged over multiple simulation runs.
