摘要
为了实现电磁诱导透明现象,设计一种基于超材料的同时磁场激发的明-明模耦合电磁诱导透明结构,结构由双U型环和双圆环组成。通过改变两类构造的几何参数,实现了在特定频率下的共振,并分析了基于硅基半导体和石墨烯的电控类电磁诱导透明结构。模型分析结果显示,当耦合距离从5.0 mm到6.0 mm时,双U型环和双圆型环的透射谱中未出现传输窗口。电控类电磁诱导透明结构实验表明,通过调节费米能级,可以有效地调控超材料的透射特性。当费米能级提升至0.5 eV时,透射峰的强度降至59%。研究结果为电磁诱导透明结构的设计和控制提供了理论基础和技术路线。
In order to realize the phenomenon of electromagnetically induced transparency,an electromagnetically induced transparency structure with bright bright mode coupling based on metamaterial and simultaneously excited by magnetic field was designed.The structure consists of double U-shaped rings and double circular rings.By changing the geometric parameters of these two types of constructions,resonance phenomena were achieved at specific frequencies.In addition,electronically controlled electromagnetically induced transparent structures based on silicon based semiconductors and Graphene were also analyzed.Further model analysis results show that when the coupling distance S=6.5 mm,there is a narrow transparent window in the transmission spectrum of the double U-shaped ring and the double circular ring that appears within a wide frequency range.At the same time,the experiments of electronically controlled electromagnetically induced transparent structures show that the transmission characteristics of metamaterial can be effectively controlled by adjusting the Fermi level.When the Fermi level is rised to 0.5 eV,the intensity of the transmission peak decreases to 59%.These results provide a new theoretical basis and technology roadmap for the design and control of electromagnetically induced transparent structures.
