High performance terahertz polarization converter based on double V-shaped metasurface

In this paper, a metamaterial-based terahertz polarization converter that can efficiently rotate linear polarization of electromagnetic (EM) wave into its orthogonal one in wideband is proposed. The simulation results show that the proposed polarization converter is able to rotate a linearly polariz...

More Information
Summary:In this paper, a metamaterial-based terahertz polarization converter that can efficiently rotate linear polarization of electromagnetic (EM) wave into its orthogonal one in wideband is proposed. The simulation results show that the proposed polarization converter is able to rotate a linearly polarized wave into a cross-polarized wave in the frequency range from 0.14THz to 0.31 THz, with an average efficiency of 97%. Attributing to the high performance, the proposed polarization converter can be used in the area of terahertz spectroscopy, imaging and communications.
