摘要：

In this paper, a method for broadband polarization-dependent coding metasurface design is proposed. Single-polarized unit cells are employed due to their single-polarized phase manipulation with little effect on cross-polarized phase in broadband. The equivalent circuit of these unit cells is developed to analyze the mechanism. Because of single-polarized phase manipulation, coding metasurfaces for different polarizations can be designed separately. The polarization-dependent coding metasurface can be obtained by simply combining them into a sharing aperture. Simulated and measured results prove that our method offers a simple and effective strategy for broadband polarization-dependent metasurface design.
