Figure 9. Measurement of RCS reduction versus frequency.

Figure 9

The proposed metasurface and a metallic plate with the same size are measured, respectively, and then the RCS reduction is obtained by subtracting the results. (a) Measured and simulated RCS reduction with chess-board coding shown in Fig. 5(d). (b) Measured and simulated RCS reduction with optimized diffusion coding shown in Fig. 5(f).
