Abstract
In this letter, a dual-band transmission-reflection-integrated coding metasurface is proposed. It possesses frequency- and polarization-dependent properties and is capable of effectively generating and controlling splitting beam patterns. The multilayered coding unit mainly consists of a multistrip layer, a double arrow layer, and metal gratings along two ortho- gonal directions. Unlike individually reflective or transmissive metasurfaces that operate at only a single frequency point, the proposed metasurface can realize reflected and transmitted beam-splitting patterns under vertically polarized and horizontally polarized incident plane waves at both 135 GHz and 225 GHz, respectively. The proposed metasurface can independently realize different beam-splitting patterns by using corresponding coding sequences at two separate frequencies. For demonstration, the proposed metasurface is fabricated and measured, showing a reasonable agreement with simulated results.
期刊介绍：
IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
