摘要：
In recent years, the use of metasurface to reduce radar cross section has been paid much attention with the rapid development of detection and stealth technology. In this paper, a 2 -bit coding metasurface has been designed to realize broadband of Radar Cross Section (RCS) reduction. The designed metasurface consists of four units "00", "01", "10", "11". Then, Genetic Algorithm (GA) and Antenna Array Theory are used to optimize the arrangement of elements on the metasurface to obtain the optimal scattering characteristics. The measured result coincides with the simulated results. The RCSr curves of simulation and experiment reach below10dB in the broadband range of 4.4-16.3GHz almost simultaneously. Compared with the metal plate, the beam manipulation capability of this 2 -bit digital metasurface is obviously enhanced.
