摘要：
We proposed a chiral switchable metamaterial using MEMS technology in the terahertz frequency region. Deformation of a flat metal spiral unit of the metamaterial creates three-dimensional spirals, and symmetrical chiral switching of the spiral could be performed by selecting the deformation directions; upper or lower. Ellipticity modulations amplitude as large as +/- 28 degrees could be obtained in 1.08 THz, and optical responses were numerically analyzed.
