摘要：

In this paper, we proposed a cross-polarization converter that simultaneously works at four terahertz regime in the transmission mode. The cross-polarization converter is composed of four metasurfaces and three dielectric layers interlaced with each other. It's able to efficiently convert a linearly polarized wave to its cross-polarized wave at 0.991.09THz, 1.10-1.29THz, 1.39-1.51THz and 1.60-1.65THz respectively. The neighboring unit cells of the central metasurface layer of the cross-polarization converter exhibit strong electromagnetic (EM) coupling. This converter takes favorable advantages of more operation frequency bands for linear polarization conversions, which indicating potential applications in terahertz detectors, antennas, imaging, communication systems and so on.
