Abstract

Benefit from its subwavelength scale, metasurface has been widely used at the area of holograms. However, the existing researches about meta-hologram are mostly based on the illumination of propagating wave. In this condition, the ability of information coding of the evanescent wave is wasted. Thus, we demonstrated a complex structure which consists of prism and metasurface. This structure realizes the evanescent wave illumination, and extracted the image information from the evanescent wave region successfully. This scheme shows large potential in the area of information storage and information encryption.
