In this paper, we will introduce an ultrathin metasurface, which is based on de- structive interference between the incident and reflected waves and therefore leads to dramatic decrease of backward RCS. The main lobe and some of the side lobes of the scattering pattern of the targets could be suppressed significantly. When the phase shifts of metallic patches of the metasurface are randomly distributed, the reflected energy from the random metasurface will be scattered in various directions, resulting in the RCS reduction. By comparing the scattering pattern of the designed metasurface and a pure metallic plate with the same dimensions, the backward RCS can be reduced by more than 10 dB within the whole X band.
