摘　　要：论述了左右手介质交替复合组成的一维布拉格反射器的设计原理及该反射器件的异常窄带传输特性.得到:在左右手材料交替结构的布拉格反射器中,无论左手介质层与右手介质层的光程差是否能相互抵消,这种异常窄带传输都存在;如果它们不能相互抵消,则要求每个介质层的反射系数不能太小.One dimensional Bragg reflectors which consists of RHM and LHM alternative structures and unusual narrow transmission of the reflectors was discussed. In the Bragg reflectors, these unusual narrow transmission bands may exist no matter whether the optical length of a LHM layer completely cancels that of a RHM layer. However, if they can not cancel each other, it is required that the reflection coefficient for each interface is not too small.
