基于FDTD的1-D和2-D PGB结构的研究

RESEARCH ON 1-D AND 2-D PBG STRUCTURE BASED ON FDTD METHOD

用FDTD数值方法研究了用于微带传输线的 1 D和 2 D的PBG(PhotonicBand Gap)光子带隙结构 .并且制作了不同PGB结构的电路用于实验 ,以比较计算结果和实验结果 .详细分析了PGB结构的周期的大小和个数、单元的尺寸和形状等方面对其形成的阻带的影响 。

The 1-D and 2,-D photonic band-gap(PBG) structure used in microstrip was studied by using FDTD technique. Several PBG circuits were fabricated for comparing the calculational results with experimental ones. The effects on the stopband formed by PBG structure were analyzed detailedly, which brought form the length and numbers of period of PBG structure, unit's size and shape, etc., and conclusions were given.
