Polarization properties provide a controlled degree of freedom in the process of light propagation. Efficiently manipulating polarization states plays a pivotal role in the areas of electromagnetic wave detection and information communication. In this work, we propose a chiral metamaterial that is comprised of an array of 90°-twisted E-shaped resonators with incorporated vanadium dioxide films. The hybridized chiral metamaterial allows us to effectively modify the conductivity of vanadium dioxide utilizing a thermal trigger. A thermo-controlled cross-polarization conversion can be realized. The phase transition metamaterials may open an opportunity in the THz regime to acquire a variety of functionalities, such as tunable filters, modulators and switches.
