摘要

数值仿真研究了内嵌钛酸锶钡薄膜夹层的金属网格谐振单元人工电磁媒质的谐振行为. 垂直电磁波激励下, 电磁响应频率随着内嵌夹层钛酸锶钡薄膜介电常数的变大呈现红移, 调谐率为22.6%. 本文提出的人工电磁媒质调谐方法只需要以结构单元的上下两层金属图形本身作为电极对内嵌夹层钛酸锶钡薄膜施加电压, 极大地简化了可调谐人工电磁媒质的制备及应用, 在太赫兹人工电磁媒质调制器等方面具有潜在的应用.

We present the tunable resonance behavior of laminated metal mesh metamaterial embedded by barium strontium titanate (BST) thin film. The electromagnetic frequency response shows a redshift when the dielectric constant of BST thin film increases, and the tunability is about 22.6%. For the tunable metamaterial proposed in this paper, the structural unit of metal graphics is used as electrodes to apply the electric potential, which simplifies the preparation and application of tunable THz metamaterials greatly. It has potential application in the THz media modulators.
