摘要
用传输式谐振腔法测量了Li-铁氧体/Bi-Sr-Ca-Cu-O-超导体/聚偏氟乙烯三元复合材料的微波(8-11GHz)复数介电常数和磁导率。复合材料的介电常数和磁导率符合对数加和规律。Bi系高温超导体的加入使复合材料的介电损耗提高了一个数量级。
The microwave permittivity and permeability of the Li-ferrite/Bi-Sr-Ca-Cu-O-superconductor/polyvinylidene fluoride composites were measured with the transmission resonant cavity. Both of them conform with the logarithm-additive principle. The dielectric loss of Bi-system superconductor-impregnated composites was increased by one order of magnitude.
