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...
time of 5 ps and recovered within 200 ps.A coupled oscillator model is utilized to explain the origin of controllability.The experimental results agree very well with the simulated and theoretical results.These EIT metasurfaces have the potential to be used as an ultrafast THz optical delay ...
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...
A design of switching electromagnetically induced transparency (EIT) reconfigurable metamaterials in terahertz (THz) regime is demonstrated theoretically. ... L Wang,TY Li,XJ He - 《Integrated Ferroelectrics》 被引量: 3发表: 2015年 Reconfigurable chiral metasurface based on vanadium dioxide: Modulation...
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 ...
Once the metasurface samples are processed, their functions have already been restricted. The dual-function device designed in this work utilizes the phase transition characteristic of vanadium dioxide (VO2). The entire layer of VO2 film is inserted between the double metal mi...
A THz metasurface biosensor was then designed. Its resonance peak located at the common THz peak of both vitamins, enhancing the THz waves–vitamin molecules interaction. With this THz metasurface biosensor, we finally analyzed the peak shifts in response to varying concentrations of VC and VB9. ...
