Abstract

We experimentally and numerically investigate spectral response that resembles electromagnetically induced transparency (EIT) phenomenon by using two planar metamaterials. The one of them consists of a cut wire (CW) with low quality factor and two SRRs with high quality factor, the other consists of a split ring resonator (SRR) with high quality factor located within a closed ring resonator (CRR) with low quality factor. By using FDTD simulation, we investigate the detailed mechanism of EIT-like phenomenon that occurs in the coupled system between two bright resonant modes.
