Recently, reconfigurable metasurfaces integrated with adaptable devices have demonstrated exceptional dynamic controllability across various applications, garnering considerable attention. However, many reported metasurfaces, particularly those supporting dual-polarization adjustability, exhibit limited broadband electromagnetic performance. To address this limitation, we propose a dual-polarized reconfigurable intelligent surface (RIS) with a distinctive metal layer design. Our prototype, which consists of 6 × 6 units, has been experimentally validated for its broadband performance. This RIS enables simultaneous beam control, including both beam deflection and vortex beam generation, over a frequency range from 1.8 to 2.4 GHz, achieving a fractional bandwidth of 28.6% for dual-polarized waves. By expanding polarization functionality, our work provides a solution for enhancing channel capacity in communication systems, presenting promising applications in wireless communication.
