摘要:

本文研究了两个耦合开口环谐振器的辐射特性。由于电磁耦合,在结构中诱导出两种混合磁等离子体激元模式。计算结果表明,杂化效应大大抑制了结构的辐射损耗。这导致了一个显着的增加,在耦合系统的Q-因子相比,单一的SRR。通过调节两个谐振环之间的距离,由于不同的电磁耦合强度,Q因子相应地改变。这导致了一种耦合结构,其用作具有可调Q因子的新型纳米腔。

英文摘要:

This paper investigates the radiation properties of two coupled split-ring resonators (SRRs). Due to electromagnetic coupling, two hybrid magnetic plasmon modes were induced in the structure. Our calculations show that the radiation loss of the structure was greatly suppressed by the hybridization effect. This led to a remarkable increase in the Q-factor of the coupled system compared to the single SRR. By adjusting the distance between the two SRRs, the Q-factor changed correspondingly due to different electromagnetic coupling strengths. This resulted in a coupled structure that functioned as a new type of nanocavity with an adjustable Q-factor.
