电磁波在塔尖型 ZnO 纳米阵列表面的反射摘 要:根据 ZnO 纳米阵列与蛾眼的微观结构的高度相似,借鉴目前人们对光在蛾眼表面的反射的讨论方法,利用菲涅耳系数矩阵法,采纳 MATLAB 计算出当电磁波垂直照射在 ZnO 纳米阵列表面时的反射率
最后对理论结果和实验数据进行对比分析
关键词:ZnO 纳米阵列;蛾眼;菲涅耳系数矩阵法;反射率Abstract:According to highly similar of microstructure of ZnO nanoarray and moth eyes, taking examples from the research methods that some people have done of light reflection of the moth eyes surface, using the Fresnel coefficient matrix method and MATLAB software, the reflectivity of ZnO nanoarray surface when electromagnetic wave vertical illuminate in it can be calculated
Finally the theoretical results and experimental data are compared and analyzed
