Dual-Polarized Reflective Metasurface Based on Cross-Shaped Resonator for 5G Wireless Communication Systems at 28 GHz

In this paper, the design of a dual-polarized reflective metasurface for 5G wireless communication systems at 28 GHz is presented. The metasurface configuration is composed of an array of cross-shaped resonators of different sizes that are regarding to an organization of reflection phase based on energy surface channeling technique. By properly designing the metasurface on a surface area of 15λ
