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.
