本論文研究Drude Model Function及使用常見金屬的參數導出金屬在紅外波段的光學性質。利用金屬的臨界頻率及電子振盪頻率與複數介電常數的關係，求出金屬在紅外波段的複數折射率。
而後利用複數折射率計算出在紅外波段的肌膚深度及垂直入射的反射光譜。依金屬的性質分成反磁性金屬、順磁性金屬及鐵磁性金屬，代入計算。
最後，由計算結果做出結論。期待未來能使用其它方式得出金屬的光學性質並修正Drude Model Function於可見光不準確的部份。

In this thesis, study Drude model function and derive optical properties of general metals in IR used parameters of metals. We obtain the complex index of refraction from the relationship with critical frequency and the damping frequency of metal and the complex dielectric constant.
To obtain the skin depth and the spectrum of reflection of zero degree of incident angle used the complex index of refraction. We have individual calculation of classification of metals, diamagnetic, paramagnetic, and ferromagnetic.
In conclusion, in order to modify the inexact part of Drude Model Function in visible light, we expect to obtain optical properties by other method.
