The simulation parameters (amplitude and phase diagrams together with the structure’s phase distribution). Intensity distributions (simulation results) for different phase mismatch for ideal diffractive lens. Simulations were conducted for introduced phase delays as follows: 0.3, 0.5, 0.7, 0.9, 1.0, 1.1, 1.3, 1.5, and 1.6, shown in (a)–(i), respectively.
