A Single-Layer Integrated Coding Metasurface with Flexible Beam Controlling

This paper presents a single-layered coding metasurface with inherently integrated feeding source. It alleviates the feeding blockage and alignment issues in conventional coding metasurface, and achieves a low-profile dimension. The working principle of the proposed coding metasurface is introduced followed by an example demonstration working at millimeter-wave band. It is applied with a chessboard coding sequence, and achieves the beam splitting performance with a compact size.
