Figure 1 | Schematic illustration of quasicrystal metasurface holography.

Caption

The demonstrated QCMs can reconstruct holographic images and display diffraction patterns simultaneously. Silicon nanofins are arranged in the Penrose tiling pattern as illustrated by the 2D color image on the surface of the quartz substrate to form the QCM. The letter “A” chosen as a holographic image is reconstructed at the predefined distance by the phase distribution of the QCM. And the far-field diffraction pattern with ten-fold rotation symmetry is generated due to the quasi-periodic array. The unit cells in the bottom right corner indicate the cyan thick rhomb and pink thin rhombs of Penrose tiling.
