    單負材料光子晶體光學性質之研究
    (2011) 吳聲志; Sheng-Chih Wu
    In this thesis, we shall study the optical properties for the one-dimensional photonic crystals (PCs) containing the single-negative (SNG) materials. Three main topics are involved. In the first part, we consider a PC that has a period of ENG-MNG bilayer, where ENG means the epsilon-negative material and MNG is the mu-negative material. We investigate the photonic stop band and passband structure based on the transfer matrix method. In the second part, we study the optical properties for a SNG Fibonacci PC. With this quasi-periodic structure, we show that the photonic band structure is strongly dependent on the number of Fibonacci sequence. The third topic is to study the transmission properties in a defective SNG. The resonant tunneling spectrum will be investigated in the symmetric and asymmetric structure. The defect modes are closely related to the thickness of the SNG layer in addition to the thickness of the defect layer.
