Experimental verification of left-handed metamaterials composed of electric and magnetic resonators

  • 摘要: 加工、制作和测试了由电谐振器和磁谐振器构成的左手材料.首先分别测试了电谐振器、磁谐振器各自的传输频谱,得到各自的负参数区域,然后测试了由电谐振器和磁谐振器构成的左手材料的传输频谱,并提取了其等效介电常数和磁导率.实验结果表明,在电谐振器和磁谐振器各自传输禁带的重合区域,出现了一个通带,在该通带内,等效介电常数和磁导率同时为负,验证了材料的左手特性.
    Abstract: Left-handed metamaterials were fabricated and tested.As the first step in the test,the transmission spectra of electric resonator array and magnetic resonator array were measured,from which their respective negative parameter regions can be determined.Then,the transmission spectra of the left-handed metamaterial composed of electric and magnetic resonators were obtained.From the measured scattering parameters,effective permittivity and permeability can be retrieved.The experiment results show that there is a pass-band in the overlapping region where there is a respective stop-band for both the electric and magnetic arrays.In this pass-band,both the effective permittivity and permeability are negative,which verifies the validity of left-handed metamaterials composed of electric and magnetic resonators.
