A polarization-independent dynamic unit cell in the shape of “Tian” is designed, which is composed of vanadium dioxide (VO2) thin films and gold patterns. Utilizing the phase transition characteristics of VO2, the designed unit can effectively control the amplitude of incident terahertz waves. Furthermore, based on this dynamic “Tian”-shaped unit cell, a static unit cell (without VO2) is developed for designing encrypted holography. Simulation results demonstrate that in the insulating state, both dynamic and static units produce identical amplitude modulation of incident terahertz waves, thereby achieving information encryption. When heated to transition VO2 to its metallic state, the dynamic unit alters its original amplitude response, enabling polarization-independentSholographic imaging. This approach exhibits broad application prospects in dynamic optical encryption, information storage, and anti-counterfeiting fields.
