摘要:Hollow carbon spheres (HCSs) and HCS/ZnO@C composite are synthesized by the reaction of zinc with sucrose and glycerol, respectively. The electromagnetic parameters of the HCSs and HCS/ZnO@C composite are measured by a coaxial line method. Both the real and imaginary complex permittivities and the loss tangent for the HCS/ZnO@C composite are larger than those for the HCSs. The electromagnetic absorption properties of the HCS/ZnO@C composite are advantageous over those of the HCSs, not only in band width but also in absorber thickness.
