Liquid-Crystal-Based Electrically Tuned Electromagnetically Induced Transparency Metasurface Switch

Abstract In this study, a structure to realize a switchover between two different responses of electromagnetically induced transparency (EIT) was designed and implemented by simulation. Taking advantage of the anisotropy in the structure and the coupling between the radiative and dark elements, a me...
