By computer simulation and calculation , the relation between the reflectivity and the structure parameters of such gratings are presented . these results show that a glass grating can achieve antireflection over almost the whole visible light waveband for unpolarized light , while a silicon grating with a columned grid substrate also can achieve low reflectance over as a broad field of view as a tapered silicon grating structure can , but it can be fabricated more simply
理论分析发现硅基底的圆柱形网格光栅能够在比较大的视场获得比较低的反射率，具有特定参数结构的低反射率硅基底圆柱形网格光栅可以获得与专为大视场设计的金字塔形网格光栅相同的视场角，但它的制作更容易，更简单。
A reflective polarizer based on a double - layer subwavelength metal - dielectric grating structure is presented here . numerical simulations show that at normal incidence , this polarizer reflects light polarized perpendicular to the grating lines ( transverse magnetic polarization ) , but strongly absorbs parallel - polarized light ( transverse electric polarization ) . the polarization extinction ratio is very high
理论计算表明，零角度入射时，该光栅结构在可见波段对tm波有很高的反射率，而对te波强烈吸收，即可获得很高的反射光偏振比，可以作为理想的集成偏振器件。
