摘要
制备了β Ni(OH) 2 、β Ni(OH) 2 Co和β FeOOH纳米粉末作为新型损耗介质 ,测量了其频率反射特性。结果表明制备的纳米粉末不仅可以吸收电磁波 ,而且吸收性能优于其他一些常用的吸收材料 ,其最大吸收值可以达到 4 0dB。
New lossy medium is the most important part in the research of Radar Absorbing Materials (RAM). As a kind of new material, nanometer materials have shown a bright application perspective in the broad fields of astronautics, electronics, metallurgy, chemistry, biology and medicine. β\|Ni(OH)\-2, β\|Ni(OH)\-2\|Co and β\|FeOOH nanometer powder were prepared as the new absorbing materials, and the reflective\|frequency curves of nanometer powder were measured. Results indicated that the nanometer powder could absorb the radar wave, which reflective was better than some typical absorbing materials and come to 40dB between 8～18 GHz.
