对可见光区开口环谐振腔（SRR）的负磁导率进行了理论研究。在我们的计算中，我们考虑了电流在金属SRR内部的延迟，以便精确地估计SRR的磁导率。结果表明，具有小电容的银SRR阵列在整个可见光范围内均表现出负磁导率。还讨论了SRR元件的填充因子与磁导率的关系。(c)2005 Elsevier B.V.保留所有权利。
Negative magnetic permeability of split ring resonator (SRR) is theoretically investigated in the visible light region. In our calculations, we considered the delay of the current inside the metal SRR in order to estimate the permeability of the SRR precisely. From the results, the silver SRR array with small capacitance exhibits negative permeability in all the visible range. The dependence of the permeability on the filling factor of the SRR elements is also discussed. (c) 2005 Elsevier B.V. All rights reserved.
