摘　　要：基于高频射线理论,并通过Fermat原理以一致的形式讨论了左、右手媒质界面上电波或光波的折射特性.在所得折射定律的基础上结合引入相位的辛空间坐标,对矩阵光学进行了推广.相应传输理论的表示仍然保持了Gauss理论的辛几何本质,从而可以适用于左、右手媒质混合的系统.Refraction of electromagnetic or optical waves on the interface of LHMs and RHMs is studied by the uniform approach on the basis of the high frequency ray theory through the application of Fermat＇s principle. And then the matrix optics is generalized through the combination of the refraction law gained and sympletic coordinates with phase items. The relevant expression for ray transmission can maintain the essence of the symplectic formulation and have the application in the RHMs and LHMs mixing optical systems.
