The fabricated metasurfaces, the measurement platform and the far field results. (a) The fabricated metasurface is place on the sample stage. (b) The setup of a bistatic RCS test platform. (c) The radiation image at φ = 90° has been simulated with varying angle θ. The horizontal axes represent incidence frequency and the angle of θ, respectively. The vertical axis depicts the RCS in dB. (d) The measured far field performance.
