非轴向传输下手性雕刻氧化锆薄膜的光谱传输
Spectral Remittances of Chiral Sculptured Zirconia Thin Films in Non-axial propagation
摘要:
采用分段均匀近似方法和Bruggeman均匀化方法,考虑非轴向传播时介电函数的色散,计算了右手手性氧化锆雕塑薄膜的透射和反射光谱。在交叉极化反射率中观察到第一和第二布拉格峰,并且很明显,增加方位角显著影响线偏振态的光谱。这与圆偏振态相反。
英文摘要:
The transmission and reflection spectra from a right-handed chiral sculptured zirconia thin film are calculated using the piecewise homogeneity approximation method and the Bruggeman homogenization formalism and considering that the dispersion of dielectric function happens in non-axial propagation state. First and second Bragg peaks were observed in cross-poloraized reflectances and it became clear that increasing the azimutal angle affects the spectra of linearly polarized state significantly. This is opposite to circularly polarized state.
