Numerical simulation results for close cavity selective superoscillation generation.
(a) The time-averaged electric field amplitude across the field generation domain. The white dashed line denotes the image plane. (b) The simulated waveform along the image plane z = 0 (blue, solid), plotted against the design waveform (red, dash-dot) and the diffraction-limited sinc function (green, dashed).
