在本文中，基于电磁感应透明的模拟，提出了一种由耦合辐射谐振器和暗谐振器组成的低损耗磁性超材料配置。进行全波数值模拟以验证超材料。给出了超材料的吸收曲线、透射谱、表面电流分布和有效本构参数。这些结果显示出低损耗的透明度窗口和负值有效磁导率的强烈分散，彼此吻合良好。
In this paper, a low-loss magnetic metamaterial configuration consisting of coupled radiative and dark resonators is proposed based on analog of electromagnetically induced transparency. Full-wave numerical simulations are carried out to validate the metamaterial. Absorptions curves, transmission spectrums, surface current distributions, and effective constitutive parameters for the metamaterial are presented. These results, showing a low-loss transparency window and strong dispersion in the effective permeability with negative values, are in a good agreement with each other.
