| 摘 要： | 以NiZn铁氧体为主吸收剂,添加其他介质制成复合电波吸收材料,经垂直和平行磁场磁织构化处理后,在7.5~12GHz波段测试其吸波性能,发现样品的最大反射衰减量由原来的30.5dB分别增高到36.0dB和31.7dB,匹配厚度略增,面密度略降,吸收峰移向低频,10dB带宽略增.垂直和平行磁场织构化的双层结构,其吸波性能与单层相比有所改变.

| Abstract: | NiZn ferrite based EM wave absorption materials were prepared. The samples were solidified under parallel and vertical magnetic field. The absorption properties in the range of 7.5-12GHz were investigated .We find that the maximum absorption loss of vertical and parallel magnetic field treated samples increases from 30.5dB to 36.0dB and 31.7dB respectively, matching thickness increases slightly, the area density decreases slightly, the aborption peak shifts to lower frequency and 10dB bandwidth increases. Compared to single layer absorption materials, the absorption properties of double-layer samples with vertical and parallel magnetic texturing change. |
