Broadband Terahertz linear-to-circular polarization converter based on metasurface
Effective manipulation of polarization of electromagnetic(EM)waves has drawn a lot of research interests in many fields,such as the terahertz(THz)technology.In this paper,a broadband linear-to-circular(LTC)polarization converter based on metasurface is proposed in THz frequency.The proposed converter consists of periodic unit cells which are formed by patterned metal strips,a dielectric layer,and a fully reflective gold mirror.In the frequency range of 0.536-1.270THz,the converter can convert linear polarization wave into circular polarization wave with the axis ratio less than 3dB.The simulated results indicate that the relative bandwidth reaches 81.28%and the efficiency is higher than 74%,thus,the broadband LTC polarization conversion has been realized.
