Fig. 1: Reflective chiral meta-holography.
From: Reflective chiral meta-holography: multiplexing holograms for circularly polarized waves
Images (a) “L” and (b) “R” are reconstructed at the same position for illumination with circularly polarized waves of opposite handedness. Blue cells only reflect LCP, and red cells only reflect RCP, as shown by Fig. 2. The meta-hologram has the unusual property that it does not reverse the handedness of circularly polarized waves upon reflection
