分别用矩形谐振腔微扰法和波导传输线法测量了三维连通网络的陶瓷及其同质粉末压片的电磁参数的温度特性和频率特性。结果表明，无论是磁性还是非磁性三维连通网络陶瓷在较宽的温度范围及整个测试频段内都比其同质粉末具有更大的电磁损耗，这种损耗差异来自它的三维连通网络结构特性。三维连通网络结构使材料电损耗的增加远远大于磁损耗的增加。三维网络陶瓷的这一特点，为研制兼具耐高温、宽频、廉价于一身的结构吸波材料提供了新思路。 |

The dielectric and magnetic parameters of 3D net ceramic and their chips with the same components were measured by rectangular cavity perturbation method and wave-guide transmission line method, respectively. The results showed that the dielectric and magnetic loss of 3D net ceramic were obviously larger than those of their same content chips in a wide range of temperature and the whole range of measuring frequency. The increase of dielectric loss was much higher than that of magnetic loss, that is due to intrinsic characteristics of the 3D net structure. A new way will be supplied to find a novel electromagnetic absorbing material with the characters of high-temperature resisted, wide-frequency absorbing and inexpensive. |
