中文摘要：
通过把负磁导率材料SRR阵列置于高性能电流变液中,研究了电极加载方式、电流变液浓度、电流变液类型以及电场强度等因素对浸入电流变液中的SRR阵列谐振频率的影响.实验表明,电极加载方式对SRR阵列的磁响应有重要的影响;在容器盒中充满电流变液之后SRR阵列的谐振频率往低频发生了移动,并且可以通过改变外加电场强度来调节,最大的调节范围为130MHz.数值计算结果表明SRR阵列的有效磁导率在谐振频率附近为负值,并且有效磁导率为负的频率范围也可以通过改变外加电场强度来调节.
英文摘要：
We experimentally studied the effects of certain factors, such as the ways of loading of electrodes, the concentration of ER fluids, the type of ER fluids and intensity of applied electric fields, on the resonant frequency of split-resonant ring array infiltrated in ER fluids. The experimental results show that the way of loading of electrodes has important effects on the magnetic resonance of SRR array. The resonant frequency of SRR array shows a red-shift when the ER fluid is infiltrated, the maximum shift of about 130MHz was obtained through the adjustment of the applied electric-field. Numerical simulation demonstrates that the permeability of SRR array is negative near the resonant frequency, and the frequency range of negative permeability can be dynamically tuned by the applied electric-field.
