Fig. 4

Numerically calculated phase map for an ≈300 × 300 μm2 metahologram for RCP light incident in the a forward and b backward directions. Simulated results for a 40 × 40 μm2 size Fourier-type metahologram obtained from finite-difference time-domain simulations (using FDTD Lumerical software) at a focal distance of 20 μm for RCP light incident in the c backward and d forward directions.
