A modal analysis method to describe weak nonlinear effects in metamaterials

Y. Zeng, D. A. R. Dalvit, J. O'Hara, S. A. Trugman

摘要:

本文采用严格的本征模分析方法研究了线性和弱非线性异向介质的电磁特性。当异向介质具有弱非线性时,非线性响应完全可以用线性本征模来描述。我们用这个理论来解释金属超材料的本征二次谐波光谱。我们的研究表明,超材料本征模式在优化非线性超材料响应的程度上起着关键作用,即优化不良的模式图案破坏了等离子体共振场增强的广泛公认的益处。

英文摘要:

We apply a rigorous eigenmode analysis to study the electromagnetic properties of linear and weakly nonlinear metamaterials. The nonlinear response can be totally described by the linear eigenmodes when weak nonlinearities are attributed to metamaterials. We use this theory to interpret intrinsic second-harmonic spectroscopy on metallic metamaterials. Our study indicates that metamaterial eigenmodes play a critical role in optimizing a nonlinear metamaterial response to the extent that a poorly optimized modal pattern overwhelms the widely recognized benefits of plasmonic resonant field enhancements.
