Figure 7. (A) CST simulation model; (B-F) RCS simulation results of PEC, NH, CH, NCH1, NCH2, and NCH3 at different scanning angles; (G) RCS simulation curves; (H and I) Comparative analysis of the RCS recovery values of each sample. CST: Computer simulation technology; RCS: radar cross section; PEC: perfect electric conductor; NH: nickel-only material; CH: cobalt-only material; NCH1: nickel-cobalt hybrid material (Ni²⁺:Co²⁺ = 1:3); NCH2: nickel-cobalt hybrid material (Ni²⁺:Co²⁺ = 3:1); NCH3: nickel-cobalt hybrid material (Ni²⁺:Co²⁺ = 1:1).
