WebApr 10, 2024 · The RCS reduction of metasurface A is more than 5 dB in 10.4–17.2 GHz. Metasurface B achieves RCS reduction to some extent in 7–12 GHz. The 5 dB RCS reduction bandwidth of hybrid metasurface is 6.5–16.7 GHz. In 7.3–11.9 GHz, the energy beam is deflected to reduce the reflected energy in the vertical direction.
