Abstract:	A broadband efficient reflective linear polarization converter has been developed using a metasurface. The converter consists of a U-shaped array integrated with cross dipoles. The U-shaped unit facilitates cross-polarization conversion, while the cross dipole serves to broaden the operational bandwidth. It has been demonstrated that the proposed converter can transform an incident linearly polarized wave into its orthogonally polarized reflected wave across a broadband frequency range of 18.94-51.03 GHz with a conversion efficiency exceeding 90%. The efficiency remains above 90% even as the incident angle increases to 45°, within the frequency ranges of 19.18-20.19 GHz, 26.01-30.93 GHz, and 48.8-49.77 GHz. The strong electric and magnetic responses at multi-resonances reveal the broadband polarization conversion mechanism. A prototype was fabricated to verify the performance. Measured results exhibit good consistency with the simulated ones. [ABSTRACT FROM AUTHOR]
