According to the theory of transmission line,the ideal electromagnetic parameter regions were obtained under the given conditions based on the electric loss type wave absorbing agent and the affecting factors,such as material thickness(d),incident wave frequency(f)and reflectivity(R).The modified direction of the absorbing agent and the absorbing properties under different frequency bands were predicted by comparing the simulation results with experimental results.Results showed that the dielectric loss of composites was reduced and the magnetic loss was increased,the dielectric loss angle tangent(tanδ_ε)was close to the magnetic loss angle tangent(tanδ_μ)and electromagnetic matching features were improved after loading Fe_3O_4 on the surface of the hollow structure PANI.Thus,the simulation results and the experiment results were consistent with each other.
