Abstract: The hollow and Fe nanoparticle-encapsulated nano onion-like fullerenes (NOLFs) were synthesized respectively by DC arc-discharge in water and chemical vapor deposition (CVD). The microstructures of two products were characterized and analyzed by XRD, FESEM, and HRTEM. 2~18 GHz complex permittivity and complex permeability of different carbon materials, including NOLFs, graphite, and active carbon, were measured using HP8722ES vector network analyzer for comparison. The results showed that complex permittivity and dielectric loss of two NOLFs are higher; Fe nanoparticles-encapsulated NOLFs have magnetic loss.

Key words: NOLFs, FESEM, HRTEM, Electromagnetic property, Structure characterization
