Polarization conversion is a very important electromagnetic wave manipulation method.In this paper,we investigate a high-efficiency linear-to-circular polarization and cross-polarization converter by utilizing coding metasurface.The coding particle consists of top layer metal patte and bottom metal plate sandwiched with square F4B dielectric,which can manipulate the linear-to-circular polarization and cross-polarization converter of the reflected wave simultaneously.In the terahertz frequency range of 1.0 THz-2.0 THz,the reflection magnitudes reach approximately 90％ and the axial ratio is less than 3 dB.The proposed polarization converter may lead to advances in a variety of applications such as security,microscopy,information processing,stealth technology,and data storage.
