Structures for the anisotropic and group delay coding units. (a) Simulated phase difference between the x and y polarizations, and the corresponding reflection amplitudes, for the polarization conversion coding unit shown in the inset. (b) Simulated phase difference between the x and y polarizations, and the corresponding reflection amplitudes, for the spin Hall effect coding unit shown in the inset. (c) Simulated reflection phases and (d) amplitudes for the four group delay coding units.
