摘要
A multifunctional chiral metamaterial based on the asymmetric interface condition and thermal-induced phase transition is proposed in this paper. Adding the dynamic layer to form the asymmetric interface will excite the chirality. The CDMAX can reach 0.83. Besides, the chirality state can be modified by the thermal control conductivity of VO2. CD of metamaterials reaches 0.6 at 5.425 THz when VO2 is insulated and switches to −0.4 after it turns to metallic. An application in double-encryption is envisaged and discussed. The proposed multifunctional chiral metamaterials provide a wide range of possible applications in chiral switching, sensing, communications, encryption, etc.
