在論文中將呈現具有偏振片效果次波長金屬光柵彩色濾光片之設計。
具偏振效果次波長金屬光柵彩色濾光片的幾何參數，利用嚴格耦合波分析和遺傳演算法而得到。
嚴格耦合波分析精確地解出馬克思威爾方程式或電磁波在光柵裡傳遞現象。
遺傳算法的優化方法是啟發自然選擇。設計出的光柵的週期大約100nm。
光柵高度大約在300nm到400nm之間。彩色濾色片光柵之紅光，綠光和藍光之中心波長分別為700nm，546.1nm和435.8nm，這是根據CIE 1931 當年所制定的單光波波長為依據。

In the thesis, the design of wired-gird polarized subwavelength metal grating which functioned as color filter was presented. The values of geometrical parameters
of polarized color filter subwavelength grating were obtained by the utilization of rigorous coupled wave analysis (RCWA) and genetic algorithm (GA). The rigorous coupled wave analysis was the exact solution of Maxwell’ equations for light or electromagnetic wave interacting with grating. Genetic algorithm is the optimization method inspired by natural selection. The periods of gratings were around 100nanometer.
The heights of gratings were from 300nm to 400nm. The central wavelength for the polarized color filter grating were 700nm for red light, 546.1nm for green light and 435.8nm for blue light according to CIE 1931 monochromatic light definition.
