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 Maori Design Guitar Straps resonators.Strong interaction between unit resonators in the metasurfaces yields the effective permittivity highly dependent on the lattice spacing of unit resonators.Through our rigorous theory, we provide a closed form of effective permittivity of the metasurface and reveal that the permittivity possesses a Lorentzian-type Hair Color resonant behavior, implying that the transition of the effective permittivity can arise when the lattice spacing passes a critical value.
