Abstract: In this paper, we propose a non-directional lowing scattering and flexible 2 bit coding metasurface. The four basic units with different reflection phase constituted the whole phase gradient surface by random arrangement; this coding metasurface can achieve reduction of RCS by the diffuse reflection of incident electromagnetic wave. The experimental results show that the reflectivity is -13.5 dB for coding metasurface can be achieved at 8.40 GHz, and the RCS reduction as compared with a bare metallic plate with the same size is average 10. 0 dB when deviating -30°-30° from the normal incidence. The further studied results indicate that the characteristic of RCS reduction can be kept up as the coding metasurface is wrapped around a cylinder with a diameter of 7 cm, and the RCS reduction is average 7.8 dB. This flexible coding metasurface is expected to have potential application value in the field of antenna and stealth.
