Given the anisotropy of the proposed metasurface, the Stokes parameters were used to analyze the polarization state of the transmitted wave. In equations (14), (15), χ and η are related to the phase. Fig. 9(a) illustrates the components of co- and cross-polarized transmission phases. Notably, the values of txx and tyx span from 180° to −180°. At 7.61 GHz, the txx curve transitions from negative to positive, while the tyx curve gradually decreases. Furthermore, the phase difference between txx

This paper proposes a bifunctional linear-to linear polarization converter with a sandwich structure that enables transmissive and reflective polarization conversions in different operating bands, simultaneously. The unit cell of the converter metasurface comprises an S-shaped wire, a dielectric slab, and an S-shaped slot, where the S-shaped wire and slot have complementary structures and a 30 degrees difference in orientation. When an x-polarized electromagnetic wave is incident on the proposed metasurface, most of the transmitted wave is y-polarized in the frequency range of 7.07 GHz to 7.46...
