“…Within the tuning range of the resistance (91 Ω to 1 MΩ), we can approximately treat the effect of the resistor as a perturbation to the whole system. Based on the perturbation theory, we finally derived a semianalytical relation between Γ A and R D , showing that Γ A is inversely proportional to R D (see Section SIV in the Supporting Information for details). However, lacking analytical forms of other three parameters, here we chose to determine all four independent model parameters from fitting with FDTD results, for the sake of consistency.…”

A thin screen exhibiting dynamically switchable transmission/absorption functionalities is highly desired in practice. However, a trilayer transmissive metasurface with active elements controlled in a uniform manner cannot exhibit independently controlled transmission and absorption properties due to intriguing interplays between the scattering and absorbing properties in systems exhibiting inversion symmetries. This motivates to employ the coupled‐mode theory to establish a generic phase diagram for such transmissive metasurfaces with active elements loaded in different layers tuned independently and to guide researchers design tunable metadevices with completely decoupled transmission/absorption responses. Based on such a phase diagram, a microwave metasurface is designed/fabricated with PIN diodes incorporated, and it is experimentally demonstrated that its functionality can switch from perfect transparency to perfect absorption, controlled by external voltages applied across the diodes. In addition to finding immediate applications in practice (e.g., smart radomes), the results of this study also provide a new type of tunable meta‐atom for building metasurfaces with flexible wave‐front control abilities.

“…According to the tight-binding model (TBM) in solid physics, one atom energy level is split into N levels when N atoms are combined. The photonic version of TBM for dispersive photonic systems, particularly in plasmonic materials and optical metamaterials, has been established in [12]. According to [12], the split number of the resonant peak is just equal to the number of resonators.…”

In order to obtain the means to control light polarization, we designed a structure of coupled magnetic resonators and studied its transmission properties by the 4 × 4 transfer matrix method. The incidence of linearly polarized light results in two transmission resonant peaks of left-handed circular polarization at shorter wavelengths and two transmission resonant peaks of right-handed circular polarization at longer wavelengths, respectively. Through adjusting the magnetizations, the inner left-handed circular polarization and right-handed circular polarization can be merged into one linear polarization, while the two outside resonant peaks keep their circular polarization. The polarized direction of the output linearly polarized light can be controlled by the polarized direction of incidence light. The incidence light with one polarization can output light with three kinds of polarizations through the designed structure.
