| Summary: | 碩士 === 國立臺灣師範大學 === 光電科技研究所 === 105 === In this thesis, we shall study the three theme about the optical properties of Au layers and two dielectric layers structures. In the first theme, we used transfer matrix method (TMM) to analyze 〖air/(1/Au/3)〗^N/air. In normal Incident, we could find the photonic band gap (PBG) will be shifted and become wide as the thickness of the Au layers increase. Then, we could find the PBG of TE wave and TM wave will be shifted as the angle of incident increase. But PBG of TE wave is wider than TM wave. In the second theme, we used the same method to analyze 〖air/(1/3)〗^N/Au/〖(3/1)〗^N/air. In normal Incident and γ=0, we could find the transmitted peak will be right shifted as the thickness of the Au layers increase. Then, we could find the transmitted peak of TE wave and TM wave will be right shifted as the angle of incident increase. But TE wave is larger than TM wave. In the third theme, we also used the same method to analyze 〖air/Au/(1/3)〗^N/air and air/〖(1/3)〗^N/Au/air. In normal Incident, we could find the PBG of the two structures are not dependent on the thickness of the Au layers increase. Then Then, we could find the PBG of TE waves of the two structures will become wide as the angle of incident increase, but TM waves are opposite.
