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 μ″-μ′ 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.

六角形Co / C复合材料的相似Cole-Cole半圆和微波吸收
采用水热法成功制备了六方Co / C复合材料。六角形Co / C复合材料的制备可以为制造其他金属/ C复合材料提供可能性。碳含量不同时,六角形Co / C的吸收能力也不同。通过分析电磁参数,我们证明了μ ” -μ ′曲线中的相似的Cole-Cole半圆,并且每个相似的Cole-Cole都对应于共振损失。但是,第一个类似的Cole-Cole半圆对反射损耗(RL)更为重要。最佳RL值为-47.5分贝,和最宽的带RL ≤-10分贝为5.6千兆赫。
