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...

Abstract. The development of advanced terahertz systems requires compact and reconfigurable devices capable of adaptive wavefront manipulation and electromagnetic energy control. In this work, we propose a dual-tunable VO2–graphene coding metasurface that integrates thermally switchable vanadium dioxide and electricall...

Reconfigurable terahertz polarization control is of growing importance for sixth-generation (6G) wireless communications, imaging, and sensing, yet simultaneously achieving broadband full-space operation, compact device architectures, and efficient design workflows remains a significant challenge. Here, we propose a th...
