为了研究基于旋磁材料一维光子晶体的传输属性，在麦克斯韦方程的基础上，利用磁性材料的相对磁导率张量，结合电磁场边界条件，推导出适合旋磁材料一维层状结构的传输矩阵计算公式。该公式没有经过任何理论近似，是一种精确算法，适合任何含旋磁材料一维光子晶体结构。

In order to study the transmission properties of one-dimensional photonic crystal based on gyromagnetic materials, we propose a transfer matrix method. The transfer matrix method is based on the Maxwell′s equations, the permeability tensor and boundary conditions of electromagnetic field. All the equations are taken no any approximation and suitable to any structure of one-dimensional photonic crystalcomposed of gyromagnetic materials.
