Özet
This paper presents a reconfigurable polarization conversion metasurface (Re-PCM) designed for multifunctional, wideband polarization control. By integrating PIN diodes, the Re-PCM achieves dynamically tunable reflection characteristics. In the OFF state, the metasurface exhibits wideband linear-tolinear polarization (LTLP) conversion from 22.7 to 26.8 GHz with a polarization conversion ratio (PCR) exceeding 90%. In addition, linear-to-circular polarization (LTCP) conversion is achieved across four distinct frequency bands: 9.6-10.4 GHz, 12.5-13.7 GHz, 21-22 GHz, and 27.3-27.7 GHz. In the ON state, the Re-PCM acts as a polarization converter over multiple bands: LTLP conversion from 7.21-7.55 GHz, 9.78-11.1 GHz, 18.8-22.3 GHz, and 24.9-26.9 GHz, (PCR > 95%), along with LTCP conversion at 7.1 GHz, 8.3-8.8 GHz, 12-17.4 GHz, 24.4 GHz, 27.3-27.7 GHz, and 29.3-30 GHz, where the axial ratio (AR) <3 dB. The proposed design offers a low profile, broadband, and reconfigurable control of linear and circular polarization, making it suitable for advanced microwave and communication applications.
