摘要

利用微流控系统驱动的可调谐超材料，实现了太赫兹超宽带吸收体。本文研究了一种精确连续控制微液柱高度的新技术。基于该技术，可调谐太赫兹吸收器的原理验证演示表明，吸收频率可从0.245 THz调谐到0.415 THz，调谐范围为51.5%。它为基于可调谐超材料的有源元器件创造了一个新的范例，在探测器、传感器、成像系统和隐身方面具有广阔的应用前景。

Tunable metamaterials for terahertz ultra-broadband absorption driven by microfluidics

A THz ultra-broadband absorber is realized using tunable metamaterials driven by a microfluidic system. In this work, a new technology is developed to precisely and continuously control the height of micro liquid pillars. Based on this technology, a proof-of-principle demonstration of tunable THz absorber is shown to have absorption frequency tuning from 0.245 THz to 0.415 THz with a tuning range of 51.5%. It creates a new paradigm for active metadevices based on tunable metamaterials with promising applications in detectors, sensors, imaging systems and stealth.
