Abstract
In the paper, we design a sub-wavelength level polarizer to replace the traditional polarizer in various optical applications. The structure of the polarizer is a one-dimension periodic grating. It has three layers with different materials. We do the basic design by using "Effective Medium Theorem." And we verify and improve the result by using rigorous couple-wave analysis (RCWA). In the range of visible wavelength, the polarizer has high contrast and high tolerance of incident angle in three-dimension space.
