N2 - In this paper, we introduce a simple method that enables the simultaneous manipulation of beamforming and polarization conversion, allowing for the generation and steering of high-directional or multiple beams with custom polarizations. The basic concept behind this breakthrough innovation is to create and explore a pair of metacells with high-efficiency orthogonal polarization responses and independent phase control under the same incidence wave. Based on the combination of these two types of metacells, the superposition of two orthogonal polarizations has been proposed to generate versatile output polarization, simply by adjusting the offset between the two polarization components. Additionally, specific beam with arbitrary polarizations can also be efficiently formed by analytical design of phase gradients.
