Double Fano Resonances in S-Shaped Plasmonic Metasurfaces in Terahertz Region

Double Fano Resonances in S-Shaped Plasmonic Metasurfaces in Terahertz Region

We numerically and experimentally demonstrated double Fano resonances in a simple S-shaped plasmonic metasurface in the terahertz frequency range. Apart from the electric-LC resonance and electric dipole (ED) resonance, two trapped modes are excited in two different types of asymmetric S-shaped stru...
