Quad‐Band Terahertz Electromagnetically Induced Transparency‐Like Metasurface Sensor With Geometry‐Constrained Inversion

This study proposes a quad‐band terahertz electromagnetically induced transparency (EIT)‐like metasurface sensor with geometry‐constrained parameter inversion. The device consists of three concentric ring resonators and a bottom U‐shaped resonator. A gap in the inner ring breaks symmetry, while cooperative bright–dark...
