The simulation parameters (amplitude and phase diagrams together with the structure’s phase distribution). Intensity distributions (simulation results) for different lens illumination. Diffractive structures were illuminated with Gaussian beams with different waist values (in mm) as follows: 20, 30, 40, 50, and 60, shown in (b)–(f), respectively. In case of sufficient illumination (plane wave) (a).
