摘　　要：超常介质的等效介电常数和等效磁导率可由电磁波与特定金属结构单元阵列的相互作用产生.本文用RLC串联谐振回路对这一过程统一描述,得到二者的实部在大于谐振频率的附近可为负值,虚部在任何情况下一定为正值.The equivalent permittivity and permeability of metamaterials can be generated by the interaction of electromagnetic waves with specific metal structured cell array. Using the unified description of the interaction by RLC series resonant circuit, we conclude that both the real part of the equivalent permittivity and permeability are negative when the incident wave frequency is greater but close to the resonant frequency; and the imaginary parts of them are positive in any case.
