摘　　要：从三个方面对目前的负磁导率材料谐振频率和谐振强度的调节方法进行了总结:1)改变组成材料的性质实现其谐振频率的可调;2)在SRR开口缝和内外环之间加载电容器实现谐振频率的可调;3)电激励或光照调节基底介质的介电性质实现谐振幅度的调节.展望微波段及未来红外和可见光波段可调谐负磁导率材料的研究将极大推动智能化左手材料的实现.The tunablity of resonance frequency and resonance strength of negative permeability metamaterials is a hot research problem at present. This paper summarizes the tuning ways from the following aspects：（1） Changing the property of composing medium;（2） Loading capacitors in the gap region between concentric rings and in the split region of SRR;（3） Tuning the resonance strength by changing the property of the substrate using electricity and laser. The research of negative permeability metamaterials with tunable resonance frequency and resonance strength at microwave frequency nowadays and at infrared and visible frequency in the future will push the achievement of intelligent metamaterials soon.
