摘　　要：通过理论计算,得出了平面单色电磁波在单轴各向异性左手介质中传播的特性,给出了能量传播方向与波矢方向之间的关系,结论与电磁波在通常介质及各向同性左手介质中传播显著不同。单轴各向异性左手介质中传播的电磁波被限制在一定区域内,其区域范围和介质参数直接相关。The physics characters of electromagnetic wave are derived from theoretical calculation when it spread in uniaxially anisotropic left-handed materials. The relationship is given between the energy propa- gation direction and the direction of the wave vector. The conclusion is significantly different from the iso- tropic left-handed materials or the normal materials. When electromagnetic wave spread in uniaxially anisotropic left-handed materials, it is limited within a certain region, and the region of electromagnetic wave propagation is directly related to the medium parameters.
