耦合非线性开口环谐振腔的多稳性和局部化

Multistability and localization in coupled nonlinear split-ring resonators

Nikos Lazarides, Mario I. Molina, George P. Tsironis, Yuri S. Kivshar

摘要:

我们研究了一对非线性开口环谐振器(一个“元二聚体”)的动态激励的交变磁场和磁耦合。这种类型的线性间二聚体最近已被用作三维超材料或“立体超材料”的基本组分[N. Liu { \em et al},Nature Photon. { \bf 3},157(2009)]。我们表明,非线性提供了更多的可能性,实时可调性和多种状态,可以通过改变外部字段。此外,我们证明了几乎总的本地化的能量在一个谐振器在很宽的参数范围内。

英文摘要:

We study the dynamics of a pair of nonlinear split-ring resonators (a `metadimer') excited by an alternating magnetic field and coupled magnetically. Linear metadimers of this kind have been recently used as the elementary components for three-dimensional metamaterials or 'stereometamaterials' [N. Liu {\em et al}, Nature Photon. {\bf 3}, 157 (2009)]. We demonstrate that nonlinearity offers more possibilities with respect to real-time tunability and a multiplicity of states which can be reached by varying the external field. Moreover, we demonstrate almost total localization of the energy in one of the resonators in a broad range of parameters.
