Abstract

Electromagnetically induced transparency (EIT)-like effects in gold metamaterials consisting of dipole resonators and quadrupole resonators were experimentally demonstrated in terahertz frequency region, and their transmittance characteristics were evaluated. Transmittance characteristics of the metamaterials could be controlled by the gap distance between the two resonators. At frequencies around 1.5 THz, transmittance between 82.0% and 0.9% were observed for fabricated EIT metamaterials with gap distances between 3.1 and 23.1 m.
