Gap-Size-Dependent Effective Phase Transition in Metasurfaces of Closed-Ring Resonators
We theoretically investigate a metal-to-insulator transition in artificial two-dimensional (2D) crystals (i.e., metasurfaces) of tightly coupled closed-ring resonators. Strong interaction between unit resonators in the metasurfaces yields the effective permittivity highly dependent on the lattice sp...
