Abstract

In this paper, we demonstrate a metamaterial tunable filter with liquid metal, which can be tuned by adjusting the size and position of the air gap within the liquid metal. In experiment, it measures a 2.3 GHz tuning range for the tunable metmaterial unit with the working wavelength of 8.9 GHz. The tuning of 5 × 5 unit array is also demonstrated. Different from traditional metamaterials [1, 2], the metal patterns of the tunable metamaterial filter are liquid state which can be reshaped once fabricated. The liquid state metal pattern not only advances in flexible tuning method, but also results in large tuning range for vast applications, such as tunable filter, accelerometer and optical switch.

液态金属超材料可调滤波器

本文演示了一种利用液态金属的超材料可调谐滤波器，该滤波器可以通过调节液态金属内部气隙的大小和位置来调谐。实验结果表明，该可调谐材料单元的调谐范围为2.3 GHz，工作波长为8.9 GHz。并对5 × 5单元阵列的调谐进行了演示。与传统的超材料不同[1,2]，可调谐超材料滤波器的金属图案是液态的，一旦制成就可以重塑。液态金属图案不仅在灵活的调谐方法上取得了进步，而且在可调谐滤波器、加速度计和光开关等广泛应用中具有大的调谐范围。
