Electromagnetic Scattering Suppression Based on Multi-beam OAM Metasurface

In this paper, a multi-beam OAM metasurface is designed and simulated, which can effectively achieve RCS reduction in the frequency range of 5–11 GHz. The metasurface designed in this paper has the design flexibility of the number of beams, the direction of beam offset, and the OAM mode. The design of the metasurface can effectively reduce its backscattered energy to the radar. This has important application value in stealth technology.
