Simulation and fabrication of the sample.
(a) Schematic diagram of the designed meta-hologram under LCP illumination and image with RCP in the Fraunhofer region. The map of China was drawn with Adobe Illustrator CS6 software (http://www.adobe.com/products/illustrator.html). (b) The designed phase hologram with 100 × 100 pixels for the China map shown in the inset. (c) The simulated holographic diffraction image acquired by CST. The intensity has been normalized. (d) Scanning electron microscope (SEM) image of the processed meta-hologram sample and the correlative scale bar is 5 μm. The up-right inset is a higher magnification image and the correlative scale bar is 1 μm.
