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。

英文摘要：

The metal photonic band gap structure has potentialities in the areas of high-energy accelerators, microwave vacuum electron devices, and terahertz radiation sources etc. The real space transfer matrix method in a nonorthogonal coordinate system is used to study the two-dimensional metal photonic band gap structure consisting of a skew lattice. A general formula for calculating the complete band gap structure is derived for transverse-electric and transverse magnetic modes, and the influences of the filling fraction, skew angle and cross section of the metal rod on band gap are analyzed. The results are in good agreement with results of other methods in some special cases.
