Metasurfaces have shown great potential in achieving low-cost and low-complexity signal enhancement redirection. Due to the low transmission power high attenuation issues of current high-frequency communication technology, it is necessary explore redirection technology based on metasurfaces. This paper presents an innovative metasurface for indoor redirection, featuring thin thickness, gain, wide-angle deflection.

A novel bifunctional metasurface (MS) operating at two frequencies is proposed to manipulate reflected and transmitted waves independently. The element composed of a slot sandwiched by C-shape spilt rings (CSRRs). middle layer the metal sheet etched slots, it used select polarization mode reflection transmission. Also, isolates transmission elements eliminates coupling between them. Therefore, or amplitude phase MS can be regulated corresponding single compared with current elements. This helpful shorten design time. higher achieved fewer substrate layers lower profile. operate 17.6 GHz 12.6 GHz, respectively. As proof concept, full-space multibeam generator validated both numerically experimentally bifocal metalens demonstrated numerically. provides new kind low cost, lightweight, easily modularized planar devices for microwave applications.
