Synthesis and electromagnetic properties of Al/AlOx-coated Ni nanocapsules

(a) Two-dimensional representation of RL derived from the measured and of the Ni nanocapsules-paraffin composite as a function of frequency. (b) RL of the Ni nanocapsules-paraffin composite with the thickness range from 1.3 to 3.0 mm. (c) RL of the composite with the thickness range from 4.0 to 10.0 mm. (d) RL of the composites with the different thickness as the function of frequency for simulation and experiment.
