| 中文摘要: |
| 研究了平面各向异性羰基铁/ 石蜡、铁氧体/ 石蜡同轴样品的介电常数与磁导率频谱特性,制备了平面各向异性羰基铁与铁氧体不同配比的石蜡同轴样品,并测试了样品的电磁频谱,发现以适当配比对二者进行复合后,可以发挥各自的优点。以环氧树脂-聚酰胺固化剂体系为基,按铁氧体和平面各向异性羰基铁的体积分数均为10%制备了厚1. 3 mm 的单层平板吸波材料,测试了其在8 ~18 GHz 频段内的反射损耗曲线,其最小反射值达到了-19. 7 dB,小于-10 dB 的带宽达到8 GHz。 |
| 英文摘要: |
| The spectra of permittivity and permeability of the coaxial planar anisotropic carbonyl-iron (PACI) / paraffin and ferrite/ paraffin composite samples were studied. The coaxial ferrite/ PACI/ paraffin composite samples with different volume concentration of the two kinds of particles were prepared. Their permittivity and permeability were also tested and studied which show preferable characteristics can be obtained by appropriate combinations. Using epoxy-polyamide system as the matrix resin, a single-layer coating with a 10% volume concentration of both ferrite and PACI particles was prepared, which has a thickness of 1. 3 mm. The reflection loss was tested in the frequency range of 8 ~18 GHz, which shows a minimum reflection of -19. 7 dB with a -10 dB bandwidth of nearly 8 GHz. |
