- Abstract
In this paper, we propose a new way to control the transparent far-field beam by varying coded sequence combinations based on transparent coding metasurface. As an example, an ultra-wideband and high-efficiency transparent coding metasurface is designed and measured. By elaborately arranging the coding sequences of coding meta-atoms to 1-bit, 2-bit, and 3-bit, with the transparent coding metasurface, can achieve two and four transparent far-field beam splitting and abnormal beam deflection when the EM wave is oblique incidence on the metasurface. The experimental results agree well with the numerical simulation results.
