An experimental study of the electromagnetic parameters on the carbon fiber chiral materials of composite matrix
【摘要】 以碳纤维为手性掺杂体，以Fe3O4与聚苯胺复合物为基质，制成手性复合材料．利用微波圆波导法在8.5～11．0GHz频率范围内测量了偏转角、轴比、复反射系数，计算出手性材料的介电常数、磁导率和手性参数．对手性材料电磁参数受频率和基质中Fe3O4浓度的影响进行了分析．实验结果表明用复合物作基质制作手性材料提高了电损耗、磁损耗和手性参数．
【Abstract】 The chiral material is prepared by using carbon fiber as chiral inclusions,in which the composite of Fe3O4 and polyaniline was used as matrix. The rotationangles,axial ratios and complex reflection coefficients are measured by using a mi-crowave circular waveguide method in the range 8. 5-11.0 GHz. The electromanet-ic parameters are calculated. The concentration of Fe3O4 in influenced results is ana-lyzed. The results show that dielectric loss,magnetic loss and the chirality parameters of the chiral materials of the composite matrix are raised.
