- Abstract
Both origami and kirigami arts, the strategies of mechanically affording versatile and unconventional structural transformation, have attracted huge attention in the fields of physics and material science. With the assistance of meta‐devices, origami and kirigami techniques are gradually applied to guide electromagnetic waves yet the exploration on this academic issue is still in infancy. Here, a general paradigm that inspired by origami–kirigami arts is proposed to fit the Rosenfeld principle‐based chiroptical effect. The L‐ and D‐enantiomers are implemented to tailor the aperture distribution of a fabricated meta‐film. By properly folding the meta‐film, the holographic images can be reconstructed at designated focal planes when driven by spin angular momenta for distinct frequency bands. Owing to the characteristics of flexibility and foldability, the fabricated meta‐film can be easily applied to carry and deploy, which may bring up another route for spin selective systems, camouflage, and information encryption.
