N2 - We propose to achieve wideband, high-efficiency polarization conversions of transmission waves with the synergy of the waveguide and spoof surface plasmon polariton (SSPP) modes. High-efficiency transmissions based on SSPP mode coupling and waveguide mode coupling are designed in two orthogonal directions, respectively. By designing the nonlinear dispersions of the SSPP and waveguide modes, the required phase differences for polarization conversion can be obtained in a wide frequency range. To verify this principle, two different polarization conversion metamaterials (PCMs) are designed and fabricated for linear-to-circular (LTC) and circular-to-circular (CTC) polarization conversions, respectively. It is found that the LTC polarization conversion transmittivity of the LTC PCM is greater than -0.5 dB from 7 to 12.6 GHz, and the cross-polarization transmittivity of the CTC PCM for a circularly polarized incidence wave is greater than -0.5 dB in the frequency range of 7-11 GHz, showing a wide band feature.
