| 摘 要： | 用化学共沉淀法制备BaMnZnCo -W型六角晶系铁氧体电波吸收材料。在 8～12GHz频段A～f曲线有一或两个损耗吸收峰 ,随Co2 +含量增加 ,峰值增强 ,最高达 4 0dB ,初步分析损耗吸收峰产生机制。由不同涂层厚度样品的A～f曲线 ,得出材料匹配厚度 ,加入碳纤维使匹配厚度降低

| Abstract: | In this paper, BaMnZnCo-W type ferrite microwave absorption materials have been prepared. In the range of 8～12GHz, the curves of A～f have one or two loss absorption peaks. With increasing the contents of Co2+, the peak value increases to 40dB. The mechanism of loss absorption peaks has been preliminarily discussed. By the A～f curves of different thickness samples, match thickness has been determined. The match thickness reduces with the adding of carbon fiber. |
