双手性雕刻薄膜椭圆偏振光谱中的圆布拉格区
On circular Bragg regimes in ellipsometry spectra of ambichiral sculptured thin films
摘要：
本文将广义椭圆偏振理论应用于右手双旋雕刻薄膜，从振幅透射比中提取了这种结构的振幅比和相位差。结果表明，在椭圆偏振光谱随波长突变的情况下，出现了圆形布拉格区，此时选择性圆形透射最大。
英文摘要：
The generalized ellipsometry formalism is used for a right handed ambichiral sculptured thin film.The amplitude ratios and phase differences of this structure are extracted from the amplitude transmission ratios. The results showed that the circular Bragg regimes appear with abruptly changes in ellipsometry spectrum as wavelength, where the selective circular transmission is maximized.
