| Description |
327-330
We report trapped mode in Fano-like resonance in a terahertz (THz) metameterial (MM) consisting of a concentric circular and elliptical gold rings on semi-insulating GaAs substrate. We present the finite element method (FEM) based design, electron beam lithography based fabrication and 0.2-2 THz window spectroscopic results. The trapped mode of the MM can be tuned by the angle between the major axis of the ellipse and the polarization of incident THz electric field (maximum amplitude ~100V/m). |
