Abstract

This paper proposes a dual-polarized 1-bit digitally coding metasurface. The metasurface unit is composed of a single-layer substrate structure and a metal patch, and the pin tube is located at the junction of the middle section of the cross. By controlling the on-off of the diode, the topology of the metasurface unit can be changed, resulting in a 180-degree phase difference at 6.35GHz in the case of a perpendicular incident electromagnetic wave. Digital simulations show that this structure can still maintain good performance when incident at a large angle, and has a good application prospect on digitally encoded metasurfaces.
