The active controllable metasurfaces based on electromagnetically induced transparency (EIT) have attracted great interest in the research of terahertz functional devices. We demonstrate a dual-mode controllable terahertz metasurface based on complementary plasmon-induced reflection structure. Both photosensitive...
MS, metasurface; EIT, electromagnetically induced transparency; PI, polyimide; MDK, Midkine; CMM, chlorpyrifos methyl molecules. The effect of the analyte on the behavior of the PGPP@MS biosensor can be explained by the coupled harmonic oscillator model, which describes the near-field coupling ...
A specially designed fractal metasurface-based structure was investigated as a dual-polarization converter operating in the terahertz (THz) band. The proposed converter has the ability to perform both the linear-to-cross (LX) and linear-to-circular (LC) polarization conversions. In the former kind...
Further, the metasurface can convert the Fano effect to EIT mutually, and the EIT only appears in the overcoupling state if the frequency detuning of the two modes becomes zero. Notably, the dual-EITs are established by modulating the distance between two resonators within a single lattice. ...
Active control of the electromagnetically induced transparency(EIT)analog is desirable in photonics development.Here,we theoretically and experimentally proposed a novel terahertz(THz)asymmetric metasurface structure that can possess high-sensitivity modulation under extremely low power density by integrating ...
The metasurfaces based on nanostructure film play an important role in many fields. Usually, the properties and functions of metasurfaces are limited by their structure. Once the metasurface samples are processed, their functions have already been restricted. The dual-function d...
The authors have shown a frequency shift of the resonance modes with the refractive index of an analyte coating on the metasurface. The electric field of the resonant metamaterial is strongest in the gaps of the SRR. Once the analyte is coated over the resonators and fills the gap, the ...
