摘要

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.
