Broadband Terahertz Fingerprint Metasurfaces via Localized Surface Plasmon Resonance and Electromagnetically Induced Transparency Synergy
We developed a terahertz broadband sensing chip based on the synergistic enhancement effect of localized surface plasmon resonances (LSPRs) and electromagnetically induced transparency (EIT). This chip consists of a periodic array formed by cross-shaped metasurface elements of varying sizes and E-shaped metasurface ele...
