- Abstract
Based on the theory of polarization conversion, this paper designs and implements two electromagnetic units with a 180-degree reflection phase difference in the range of 10-40 GHz. By coding and optimizing the spatial arrangement of the two basic units to obtain a metasurface, which makes the incident electromagnetic waves reflect diffusely, the energy in a single beam direction is reduced to realize the reduction of the radar cross section (RCS). The full wave simulated and experimental results of the reduction of the RCS of the metasurface have been presented. The RCS of the proposed metasurface can be reduced by more than 10 dB in the two broadband bands of 12.5-17.4 GHz and 20.5-36.2 GHz, and the maximum reduction can reach 26 dB, compared with a metallic surface of the same size. In addition, the optimized metasurface can also maintain a good reduction effect under oblique incident wave directions of 30, 45, 60, and 70 degrees. A very good agreement between simulation and measurement results is observed.
