In this work, we propose a novel spintronic-metasurface terahertz emitter for the generation and manipulation of coherent broadband terahertz waves. The ellipticity of the chiral terahertz waves can reach >0.75 over the entire 1-5 THz broadband and the polarization state can be easily controlled by an external magnetic field.Authors: Shunjia Wang, Department of Physics,Fudan University / Changqin Liu, Department of Physics,Fudan University / Sheng Zhang, Department of Physics,Fudan University / Qingnan Cai, Department of Physics,Fudan University / Peng Wang, Department of Physics,Fudan University / Chuanshan Tian, Department of Physics,Fudan University / Lei Zhou, Department of Physics,Fudan University / Yizheng Wu, Department of Physics,Fudan University / Zhensheng Tao, Department of Physics,Fudan University
