| 目的 制备高性能 NiFe1 . 98Nd0 . 02O4-Fe 双层吸波涂层。 方法 采用溶胶凝胶自燃烧法制备钕掺杂 NiFe1 . 98Nd0 . 02O4。 借助 X 射线衍射仪、扫描电镜和矢量网络分析仪对 NiFe1 . 98Nd0 . 02O4 和羰基铁的结构、形貌、电磁参数进行测试分析。 采用遗传算法对 NiFe1 . 98Nd0 . 02O4-羰基铁双层涂层的厚度进行优化设计。 结果 以环氧树脂为基体,以羰基铁和 NiFe1 . 98Nd0 . 02O4 为吸波剂的双层吸波涂层具备较好的吸波性能,厚度约 1 mm,反射率在 9 . 25 ~ 11 . 35 GHz 范围内均小于-10 dB。 结论 NiFe1 . 98Nd0 . 02O4 层和羰基铁层在吸波性能上有很好的互补性,理论优化结果和实验结果相同。 |

| Objective To prepare high-performance double-absorbing coating NiFe1 . 98Nd0 . 02O4 -Fe. Methods Nd substituted nickel ferrites ( NiFe1 . 98Nd0 . 02O4 ) were prepared using the sol-gel-autocombustion method. The microstructures, morphology and the electromagnetic properties of NiFe1 . 98Nd0 . 02O4 and carbonyl iron were characterized with X-ray diffraction ( XRD) , scanning electron microscopy ( SEM) and a vector network analyzer. The thickness of double-layers microwave absorption coating was optimized by the genetic algorithm ( GA) . Results Using carbonyl iron and NiFe1 . 98Nd0 . 02O4 as absorbents, double composite absorbing coating with thickness d = 1 mm was prepared. The results showed that the reflection loss of coating was less than-10 dB over the range from 9. 25 GHz to 11. 35 GHz. Conclusion The results of measurements showed that the microwave absorption property of NiFe1 . 98Nd0 . 02O4 and carbonyl iron were complementary to each other. The calculated RL agreed closely with the experimental results in the whole measured frequency range. |
