金属光子带隙结构在高能加速器、微波真空电子器件和太赫兹波源等方面具有重要的应用前景.基于实空间传输矩阵理论,详细研究了非正交坐标系下二维斜方格金属光子带隙结构,给出了计算横电模、横磁模完全带隙结构的一般公式,并分析了填充系数、任意斜角及金属柱横截面对带隙结构的影响.计算结果在退化为正方格情况下时,与其他方法的计算结果取得很好的一致.
The metal photonic bandgap structure has an important application prospect in high energy accelerator, microwave vacuum electronics and terahertz source.According to the theory of real space transfer matrix, the two-dimensional oblique metal lattice photonic band gap in non-orthogonal coordinate system Structure, the general formulas for calculating the full band gap structure of transverse and transverse magnetic modes are given, and the influence of filling factor, arbitrary angle and cross section of metal column on the band gap structure is analyzed. In the case, the results of other methods are in good agreement.
