摘要
为了实现高效的非线性超材料,我们研究了一种在由两个辐射耦合的短线谐振器组成的超分子中增强局部电场的方法,其中短线谐振器的共振与入射电磁波的低群速度传播同时发生。数值分析表明,在保持超分子等效电路参数不变的情况下,通过减小电极尺寸和短线谐振器电容结构的间隙,可以增强超分子内的局部电场。我们测量并比较了我们先前研究中制造的超分子中气体放电的阈值入射功率与具有缩小电容结构的超分子中的阈值入射功率。实验表明,在保持超分子共振频率不变的同时缩小电容结构,会降低气体放电的阈值入射功率,并可能提高阈值入射功率最小时的气体压强。本工作的进一步发展将使我们能够实现以大气压气体作为非线性元件的高效非线性超材料。
