The meta-disk composing of NMs has the capability to implement high-capacity optical holographic storage with angle-multiplexed strategy. With interlayer structural twist, it yields twin diffraction domains, resulting in a distinctive response with metasurface rotation. The network characteristics of TDNN can dynamically take shape with the varying angles of multiple layers of NMs, leading to a substantial expansion in design flexibility and freedom. Through the continuous playback of the meta-disk, a series of diffraction domains and innovative holographic videos emerges. NM, neuro-metasurface.
