Hexagonal Co/C composites have been successfully prepared by hydrothermal method. And the preparation of hexagonal Co/C composites can provide possibilities for fabricating other metal/C composites. With different content carbon, the absorbing capacities of hexagonal Co/C are different. By analyzing the electromagnetic parameters, we have proved the similar Cole-Cole semicircles in mu-mu' curves and each similar Cole-Cole corresponds to a loss of resonance. However, the first similar Cole-Cole semicircle has more important to reflection loss (RL). The optimum RL value is -47.5 dB, and the broadest band of RL <= -10 dB is 5.6 GHz. (C) 2018 Elsevier B.V.
