【摘要】 首次制备了不同复合基底的旋波介质 ,利用网络分析仪对样品进行了测量。实验表明 ,适当改变基底电导率或适量掺杂铁电、铁磁性物质可有效降低旋波介质的反射率 ,可有效调节复合手性材料的吸波性能 ,为研制高效、宽频、轻质的吸波材料提供了切实可行的思路。文中对测量结果进行了定性的分析 ,并与以非复合材料为基底的旋波介质进行了比较。更多还原

【Abstract】 In this paper chiral materials with different composite host for the first time are prepared and their properties are measured using network analyser. Experimental results indicate that changing conductance of the host or adulteration of magnetic materials in the host can decrease reflectance and adjust absorbing properities of the chiral materials,which offers a feasible method to prepare better absorbing materials.Finally, qualitative analysis of the results and its comparison with that of non composite host is presented.更多还原
