摘要

本文提出了一种基于热敏汞液态金属的可调谐超材料。通过3d打印技术将汞封装在玻璃管中，形成可调超材料的基本单元。超材料单元的电长度会随着周围温度的变化而改变，从而导致超材料的共振响应和负折射率发生相应的变化。对热可调氢超材料进行了理论分析。将进行hg -超材料单元的数值演示以验证所提出的设计。最后，提出了一种性能增强设计，以实现更高的温度传感精度。

Numerical demonstrations of thermally tunable metamaterials based on liquid metals

In this paper, a tunable metamaterial is proposed based on the thermal-sensitivity Hg liquid metals. The Hg packaged in the glass tube by 3-D printing technique is designed to form the basic unit of the tunable metamaterial. The electric length of the metamaterial unit will be altered with the changes of the surrounding temperature, and as a result the resonance response and negative refractive index of the metamaterial will be changed accordingly. Theoretical analysis on the thermally tunable Hg-metamaterial will be presented. The numerical demonstrations of the Hg-metamaterial unit will be performed to validate the proposed design. Finally, a performance enhanced design is proposed to achieve higher temperature sensing precision.
