Abstract

Electromagnetically induced transparency (EIT) is a quantum phenomenon which shows a narrow transparent window over a wide absorption spectrum. In recent years, however, EIT-like spectrum has been realized by using of metamaterials with the dark mode resonator [1,2,3]. These EIT-like spectra by metamterials can be explained by interactions between two metamaterials with different Q factors. As a response frequency of metamaterials depends on its structure size, EIT metamaterials offer unique prospects for future applications in wide range frequency from visible to terahertz region.
