用传输矩阵法研究微波波段准一维同轴光子晶体能隙结构
The band structure in microwave frequency for quasi-1-D coaxial photonic crystals
【摘要】 用SMA型同轴标准接头组成具有准一维晶格结构的光子晶体,测试结果表明具有明显的光子带隙结构.利用传输线等效模型和布洛赫周期性边界条件模拟分析也表明同轴准一维光子晶体具有能隙结构,理论计算结果与实验结果能很好吻合.
【Abstract】 A quasi-one-dimensional coaxial photonic crystal has been assembled from a series of “tee”,“female” and “male” connectors. With the vector network analyzer the transmission coefficient and the phase information has been measured for different structures. The energy band structure has also been calculated with the method of transmission matrix under Bloch periodicity boundary condition. The experimental results agree well with the calculated results.
