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. WebTeam Lead.

CPW-Fed Monopole Antenna for RCS Reduction in X-Band
WebMar 1, 2001 · RCS (dBsm) = 10.0 * log10(linear RCS) Therefore, it is incorrect to state that an object has a single definite value of RCS, since this value is dependent on many different variables. Average RCS over some angular sweep is generally specified for objects just as aircraft and missiles, however, RCS can vary by as much as 30-40 dB as angle changes.
