Abstract
A frequency multiplexed coding metasurface controlling beam is proposed to enrich the functions of a single metasurface. A square F4B dielectric substrate with a copper-clad bottom surface and a V-shaped and quadrangular cross-shaped metal structure is used as the unit. Applying the different responses of x and y polarized waves and optimization of structural parameters, we can obtain 1-bit coding units for the two frequency bands. The reflection phase can be modulated independently of each other. The design of a dual-band metasurface with different beam splitting effects was realized, achieving the goal of different frequency multiplexing functions on a single metasurface. An RCS reduction of 11 dB at 12 GHz and a double beam splitting at 20 GHz with a pitch angle of ±47.6° are achieved by metasurface. The test results agree well with the simulation results. The proposed metasurfaces offer a simple structure, low cost, good performance, and promising great applications in areas such as frequency multiplexed communications.
