Figure 4. (A-F) are the analysis diagrams of the bimetallic electromagnetic loss mechanism of the samples; (A-C) are respectively the real part of the dielectric constant, the imaginary part of the dielectric constant, and the tangent of the dielectric loss angle corresponding to the frequency of the bimetal; (D-F) are the real part of permeability, the imaginary part of permeability, and the magnetic loss tangent corresponding to the frequency of the bimetal, respectively. 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).
