中文摘要：
提出了一种新型光子晶体太赫兹（THz）滤波器,该滤波器包括利用线缺陷实现的波导部分和利用微腔实现的频率选择部分.应用平面波法（PWM）分析其带隙结构,然后应用时域有限差分法（FDTD）,研究THz波在此滤波器中的传输特性,结果表明,通过改变点缺陷的结构和增大某些介质柱的半径,可以使该滤波器实现高耦合效率的单信道单频率滤波.
英文摘要：
A new type of terahertz photonic crystal filter is presented,which includes the waveguide parts realized by line defects,and the frequency selection parts realized by micro cavities. The band gap property was investigated by using plane wave method （ PWM）,and then the transmission characteristic of terahertz in this kind of filter was studied by means of the finite difference time domain method （FDTD） simulation. The results show that,the filter can achieve high coupling efficiency filtering of single-channel and single-frequency,by changing the point defects structure and increasing the radius of certain dielectric cylinder. High efficiency THz-band photonic crystal filter was designed in this thesis.
