手性材料手性参数的圆波导测量方法
Principle of Measuring the Chirality Parameter of Chiral Materials in Circular Waveguide
【摘要】 本文提出了用普通微波圆波导测量系统测量手性材料复手性参数的方法。该方法还能同时测量手性材料复介电常数和复磁导率。为了得到手性参数,首先需要测量短路(样品后有金属板)和开路(样品后无金属板)时的复反射系数,及电磁波通过手性材料后的偏转角和轴比。测量结果与自由空间法的测量结果一致。
【Abstract】 This paper presents the principle of measuring the chirality parameter of chiral materials in microwave circular waveguide. It is needed to measure the complex reflection coefficients of short circuit(sample is backed with metal) and open circuit(sample is not backed with metal), rotation angle and axial ratio when microwave passes through the chiral materials. The results agree with that obtained by free space method.
