以石蜡为基底，以铜螺旋体为手性掺杂体，制作了手性复合材料，利用圆波导测量法在8．5～11．5GHz频段内测量了各样品的反射系数．分析了螺旋体的螺径、螺距、线径、环数对手性材料的反射系数的影响．结果表明，选取适当结构参数的螺旋体，可以有效地降低手性材料的反射系数。

The chiral materials are prepared by using copper helices as chiral inclusions, in which paraffins was used as matrix. The reflectance of chiral materials are measured in the range of 8.5-11.5 GHz by using the measurement method of microwave circular waveguide. The effects on the reflectance of chiral material by the diameter, the pitch, the gauge and the rings of the helices have been analyzed. The results indicate that selecting appropriate constitutive parameters of helix ...
