Abstract
We generate and investigate a self-healing pillar array with a specific phase function comprised of four engineered cubic phase plates with encoded amplitude and phase. This array shows an enhanced self-healing effect at arbitrary obstructed positions in transverse as well as longitudinal locations along propagation where its symmetrical pattern with uniform intensity distribution can be maintained. The transverse power flow in terms of Poynting vector is studied for better interpretation of the self-healing property.
