摘要
对亚波长结构抗反射表面的设计原理和设计方法进行了较详细的论述 .基于等效媒质近似理论 ,给出了一维光栅结构的等效折射率 .描述了二维对称结构的一维近似分析方法及其等效折射率估算方法 .为得到大的特征尺寸 。
A procedure for designing antireflection sub wavelength structured surfaces is discussed. One dimensional profiles are examined by using of zeroth order effective theory. An approximation of a structure periodic in two dimensions by a structure periodic in one dimension is given, and the estimation of the effective refractive index for two dimensions is presented. The hybrid structures of ridges and meshes are investigated in order to yield larger feature sizes.
