High-Sensitivity Terahertz Sensor for Liquid Medium Detection Using Dual-Layer Metasurfaces

In this article, a metasurface-based liquid sensor combined with terahertz spectroscopy is proposed to detect various liquid mediums. The sensor consists of two intersecting resonant structures with identical geometry, offering high sensitivity and resolution for index sensing. The mechanism of inte...
