中文摘要：

二种有点左手的材料(DLHM ) 被分别地作为异构的元素把电感器和电容器插入到传统的左手的材料(LHM ) 设计，它与电容器(CDLHM ) 是有电感器(LDLHM ) 和 DLHM 的 DLHM。传播光谱的特征被使用有限差别的时间域方法(FDTD ) 学习。与传统的 LHM 相比， LDLHM 的回声力量被削弱，通带被缩小，但是随插入的电感器的价值的增加，带宽被扩展。作为插入到 LHM 的电容器， CDLHM 的通带被扩展，但是通带被转移到低频率，同时，带宽随电容器的价值的增加被缩小一条新产生通带也被转移到低频率。因此，一使量子化可控制的做的左手的材料能被完成。

英文摘要：

Two kinds of controllable doped left-handed materials （DLHMs） were designed by inserting inductors and capacitors into the traditional left-handed material （LHM） as heterogeneous elements respectively, which are DLHM with inductors （LDLHM） and DLHM with capacitors （CDLHM）. The characteristics of transmission spectrum were studied by using finite-difference time-domain method （FDTD）. Compared with the traditional LHM, the resonance strength of the LDLHM is weakened and the pass-band is narrowed, but with the increase of the value of the inserted inductors, the bandwidth is expanded. As capacitors inserted into the LHM, the pass-band of the CDLHM is expanded, but the pass-band is shifted to low frequency and the bandwidth is narrowed with the increase of the value of the capacitors, meanwhile, a new generated pass-band is also shifted to low frequency. Therefore, a quantized controllable doped left-handed material can be achieved.
