From: On-axis structured beams generation via moiré and Mie resonant metallo-dielectric moiré gratings
Comparison of simulated intensity and phase pattern of on-axis structured beam obtained using (a) amplitude mask, and (b) LFG, (c) azimuthal amplitude profile of the mask and LFG, (d) graph of zeroth order amplitude profile with the variation in the duty cycle of the grating.
