摘要：

We numerically investigated a broad-band polarization conversion of linearly polarized THz in a planar metasurface. The unit cell of the proposed MM configuration is comprised of a C-shaped resonator. We studied the co -and cross-polarization transmission of the proposed geometry for different polarizations of the incident light starting from 0 degrees to 45 degrees in steps of 15 degrees. Our design promises a cross-polarization conversion of 40% in a broad frequency spectrum of 1.3 to 3.0 THz when the structure is rotated by 45 degrees with respect to the incident THz.
