Abstract

One kind of switchable, tri-band, terahertz linear polarizing rotator is presented in this paper, which consists of sandwiched metal chiral metamaterial structure composed of twisted electric field-coupled resonators in C4 symmetry and a VO2 film on substrate for active controlling. The polarizing rotation is switchable with the state change of VO2 from an insulator to metal. Simulated results consistently demonstrate that the switchable rotator exhibits extremely low loss, high polarization conversion ratio and optical activity at the three resonance frequencies. The influence of different geometric parameters of the chiral metamaterial structure is investigated to optimize the multiband rotating response of the polarizing rotator. This switchable terahertz metamaterial-based rotator has various potential applications in terahertz wave controlling and the terahertz functional devices.
