Figure 5. Electromagnetic absorption performance of ZnCo₂O₄, Zn_1-xCo₂Ni_xO₄, ZnCo_2-yFe_yO₄ and Zn_1-xCo_2-yNi_xFe_yO₄. (A) Simulated electromagnetic power loss density; (B and C) Real (ε′) and imaginary (ε″) parts of the relative permittivity; (D and E) Real (μ′) and imaginary (μ″) parts of the relative permeability; (F and G) Dielectric and magnetic loss tangents; (H and I) Radar cross-section (RCS) values; (J) Comparison of reflection loss (RL) and effective absorption bandwidth (EAB) of Zn_1-xCo_2-yNi_xFe_yO₄ with previously reported absorbers^[54-62]. EM: Electromagnetic.
