正交铁磁微丝阵列polymer复合材料的亚复合特性及其影响因素
Metacomposite characteristics and their influential factors of polymer composites containing orthogonal ferromagnetic microwire arrays
摘要：
本文研究了正交排列的Fe_（77）Si_（10）B_（10）C_3微丝对玻璃纤维增强聚合物复合材料微波性能的影响。在0外部磁场作用下，含有正交线阵列的复合材料在1 ~ 6 GHz的频率范围内显示出明显的透射窗口，表明其具有本征双负折射率特性。聚合物基体已被证明对微波性能产生协同效应，这是当Ek垂直于玻璃纤维方向时透射窗口消失的原因。等离子体频率的正交的微丝阵列复合材料是高于平行的微丝阵列具有相同的线间距，这可能是由于增强的微丝波的相互作用诱导的轴向电组件上的附加层的垂直线。所有这些特性使得这种新型正交微丝复合材料具有潜在的隐身和传感应用前景。
英文摘要：
The microwave properties of glass-fibers reinforced polymer composite embedded with an orthogonal array of Fe77Si10B10C3 microwires have been investigated. The composites containing orthogonal wire arrays display a remarkable transmission window in the frequency band of 1 to 6 GHz under zero external magnetic field indicating an intrinsic double-negative-index characteristic. The polymer matrices have proved to exert a synergistic effect on the microwave properties, which is responsible for the disappearance of the transmission windows when Ek is perpendicular to the glass fiber direction. The plasma frequency of the orthogonal microwire array composite is higher than that of the parallel microwire array with identical wire spacing; this could be attributed to the enhanced microwire-wave interaction induced by the axial electrical components on the additional layer of perpendicular wires. All these features make this new kind of orthogonal microwire composites promising for potential cloaking and sensing applications.
