An interleaved coding Janus metasurface is proposed, which can generate bidirectional functionalities with full phase control of the reflected and transmitted waves. By introducing rotation geometric parameter changes into meta-atoms, reflection transmission channels required energy distribution foci are realized. More remarkably, our approach based on a single design that arranges two types unidirectional propagating unit structures simultaneous desired properties checkerboard configuration to obtain four different holograms. The results verify excellent performances multifunctional metasurface, laying foundation for manipulation EM waves more degree freedom, promoting its applications in entire frequency spectrum.
