Abstract： The electromagnetically induced reflection (EIR) effect of graphene metamaterials has been investigated by finite difference time domain (FDTD) method. In this study, a metamaterial sandwich structure composed of silica (SiO2), gold and graphene on terahertz band is designed. By changing the width of the two ribbons of graphene length and the incident angle of electromagnetic wave, the EIR effect of the structure is discussed, and it can be found that SiO2 is a kind of excellent dielectric material. The simulation results show that graphene metamaterial is not sensitive to polarized incident electromagnetic wave. Therefore, such EIR phenomena as insensitive polarization and large incident angle can be applied to optical communication filters and terahertz devices.

摘要:利用时域有限差分(Finite difference time domain, FDTD)方法研究了石墨烯超材料的电磁诱导反射(Electromagnetically induced reflection, EIR)效应。 首先， 设计了一种在太赫兹波段上由二氧化硅(SiO2)、 金和石墨烯条组成的三层超材料结构。 然后， 讨论了石墨烯条的宽度、 长度和电磁波的入射角等参数不同的情况下该结构的电磁诱导反射效应， 并通过改变结构的中间层介质材料得出SiO2是一种优良的介电材料。 最终的模拟结果表明， 该石墨烯超材料对极化入射的电磁波不敏感。 该极化不敏感和大入射角的电磁诱导反射结构在光通信滤波器和太赫兹器件中有潜在的应用。
