A design method based on the lossy metagrating for radar cross section (RCS) reduction is proposed in this paper. According to the mechanism of the RCS reduction, the lossy metagrating with different loaded lines per supercell is studied and it is also incorporated into the metasurface to reduce RCS. The embedded metagrating provides an additional low-RCS band and it has a small effect on the original band of the metasurface. Numerical results show that the metagrating reduces RCS of the surface effectively.
