| 摘要: |
| 将传输矩阵法(TMM)用于光子晶体传输特性的研究，采用Mur近似吸收边界和周期边界来截断计算区域，计算了以TM模正入射时，二维方格子光子晶体在完整周期结构下的透过率谱；在微波波段制作了光子晶体模型，并设计了实验装置，实验与数值模拟计算结果相符合；另外还研究了有损介质光子晶体、色散和吸收介质光子晶体的传输特性，及其对光子禁带的影响。 |

| Abstract: |
| Transfer matrix method (TMM) is used to study the transmission properties of photonic crystals. The Mur absorbing boundary and periodic boundary are used respectively to truncate the computational region in photonic crystals. For two dimensional square lattice photonic crystals, the transmission coefficient versus the frequency of E-polarized incident electromagnetic waves propagating in photonic-band-gap structures is calculated in perfect periodic structures. A model of 2-D square lattice photonic crystals is designed and fabricated in microwave wavelength regions. The results of numerical simulation are in good agreement with experimental results. And also the properties of transmission are studied in 2-D loss, dispersive and absorbing materials of photonic crystals. And how the photonic band gaps are affected by loss and the dispersive absorbing materials of photonic crystals is investigated. |
