二茂铁有机磁体/陶瓷磁性复合材料的缩波功能及应用

Study on the ccompoctwave function and application for ferrocongl organic magnet/ceramics composices

用二茂铁有机磁体与陶瓷(Al_2O_3、TiO_2、BaTiO_3及微波陶瓷SrTiO_3·Bi_2O_3·3TiO_2)(简称OPM/SAT)粉末制成4种未见报道并有良好缩波功能的OPM/SAT磁性复合材料,研究了它们的组成与电磁参数(μ′,ε′),电磁损耗(μ″,ε″)及缩波性能的关系,结果表明,其缩波因子较传统的介质材料大许多倍,在高频、微波下OPM/SAT缩波材料可使微带天线的几何尺寸缩小40%,而带宽为介质天线的3倍,因此,这种新颖的有机磁性缩波材料在理论和实用上有重要的价值。

Four as yet unreported magnetic composites with a good compoctwave function OPM/SAT from ferrocene-containing organic magnets and different ceramics （Al2O3, TiO2, BaTiO3 and microwave ceramics, SrTiO3 · Bi2O3 · 3TiO2） were prepared, their contents, electromagnetic parameters （μ′,ε′）, electromagnet loss （μ″,ε″） and compactwave were studied, the result suggests that their compactwave factors are many times than the traditional dielectric materials, the OPM/SAT composited compactwave material in VHF and microwave band can be used to reduce geometric dimension of microstrip anenna by 40%, while the bandwidth will be three times of that for dielectric microstrip antennas. However, the novel magnetic compactwave materials have importance value in theory and practice.
