将平面电磁波在一维介电各向同性周期介质中的传输矩阵问题扩展至一维介电各向异性周期介质，并得到了平面 电磁波在此类介质中的传输矩阵. 此矩阵的推导主要基于麦克斯韦方程组和电磁波在介质交界面的连续性条件，即电磁波在 介质交界面的切向电场和磁场分量连续. 通过此矩阵的推导可以加深学生对“电磁场与电磁波”这门课程的理解.此矩阵也是 获得电磁波在一维介电各向异性周期介质中的场分布特性，色散关系和表面模式性质的基础. 因此，此传输矩阵对科研和教 学都有重要意义.

In this paper，the transmission matrix problem of a plane electromagnetic wave in one-dimensional dielectric isotropic periodic medium is extended to one -dimensional dielectric anisotropic periodic medium. The transmission matrix of a plane electromagnetic wave in such medium is obtained. The derivation of the matrix is mainly based on the Maxwell equations and continuity conditions of the electromagnetic wave at the interface of the medium. Namely，the tangential components of the electric field and magnetic field of the electromagnetic wave are continuous at the interface of the medium. The derivation of this matrix can deepen the students' understanding the course“Electromagnetic Field and Electromagnetic Wave”. This matrix is also the basis for obtaining the field distribution， the dispersion relation and surface mode properties of the electromagnetic wave in a one-dimensional dielectric anisotropic periodic medium. Therefore，this transmission matrix is of great significance for both scientific research and teaching.
