Figure 4
Charges of vectorial vortices generated by PAA.
Calculated angular momentum (AM) charges of (a) the vortex beam shown in Fig. 3(b) at different feeding phase of two different PAA radius of 10 and 30 μm and (b) the vortex beam shown in Fig. 3(c,d) at different feeding phase of fixed PAA radius of 20 μm. In the figures, lines are calculated by Barnett’s method and symbols are calculated by our formula for OAM and Stoke parameter of 
for SAM. Right-side insets also show the corresponding SOP distribution at feeding phase of 
.
