Sawtooth two-layer microstructures with internal and external, as well as with two internal reliefs, composed of technological and commercially available optical plastics or an optical plastic and nanocomposite material are investigated. By using the corresponding model microstructures in the frameworks of the rigorous diffraction theory, the limiting spectral and angular characteristics are estimated for sawtooth two-layer dual-relief diffraction microstructures of both types.

锯齿双浮雕两层衍射微结构的极限光谱和角度特性

研究了具有内部和外部的锯齿两层微结构，以及带有两个内部浮雕的锯齿状微结构，该结构由技术上和商业上可获得的光学塑料或光学塑料和纳米复合材料组成。通过在严格衍射理论的框架中使用相应的模型微结构，可以估算两种类型的锯齿状两层双浮雕衍射微结构的极限光谱和角度特性。
