摘要：
We propose an implementation method for broadband metasurfaces based on a one-dimensional distributed transmission-line model. Five types of one-dimensional meander microstrip-line structures are proposed and a metasurface refracting a normal incident plane wave with a 20-degree angle is implemented with those. Line length of each structure is determined from the theoretical formula of the model and the error from the theoretical value is modified by eigenfrequency analysis. Full-wave simulations are carried out, and the broadband refracting operations and the validity of the proposed method are confirmed.
