Abstract

We investigate the electromagnetic response of the concentric multi-ring, or the bull's eye, structure as an extension of the dual-ring metamaterial which exhibits electromagnetically-induced transparency (EIT)-like transmission characteristics. Our results show that adding inner rings produces additional EIT-like peaks, and widens the metamaterial's spectral range of operation. Analyses of the dispersion characteristics and induced current distribution further confirmed the peak's EIT-like nature. Impacts of structural and dielectric parameters are also investigated.

摘要

我们研究了同心多环结构（即靶心结构）的电磁响应，它是双环超材料的一种扩展，双环超材料具有类似电磁诱导透明（EIT）的传输特性。我们的结果表明，增加内环会产生额外的类似EIT的峰值，并拓宽超材料的工作光谱范围。对色散特性和感应电流分布的分析进一步证实了该峰值类似EIT的性质。我们还研究了结构和介电参数的影响。
