This paper highlights the crucial importance of polarization control within 5G wireless communication. We propose a compact polarization converter on a thin ferrite-based metasurface, which enables flexible manipulation of polarization in the reflected waves. The direction of applied magnetics bias allows the metasurface to polarize reflected waves in either co- or cross-polarization with respect to the incident wave. To optimize ferrite utilization, the adoption of a cubic lattice structure in metasurface design is recommended. This design approach has successfully delivered efficient polarization conversion and showcased impressive frequency reconfigurability. Each unit cell within the proposed metasurface can be independently controlled for spatial modulation. Utilizing the distinct material properties associated with various polarizations, the suggested metasurface exhibits remarkable potential in creating reflective intelligent surfaces. These surfaces have the capacity to substantially enhance coverage and elevate the performance of 5G networks.
