| description | This paper proposes a novel bow-tie metasurface that integrates various types of polarization conversions by optimizing traditional unit structures. The metasurface achieves wide-angle linear polarization conversion over the X-band (8–12 GHz) and has a linear polarization conversion efficiency of over 94% under normal incidence. In the Ku-band (12.4–15.6 GHz), the ellipticity value (e-value) and axial ratio calculations show that the linearly polarized waves incident along the Y axis will be effectively converted to left-handed circularly polarized waves. Additionally, in the X-band (8.9–10.5 GHz), the circular polarization and its co-polarization conversion efficiency can be maintained at 99.5%, allowing for an effective circular polarization phase shift using the Pancharatnam–Berry principle in this frequency range. |
