| Popis: | In this paper, electromagnetically induced transparency has been reported in the metal–dielectric structure that provides the platform for high-quality factor Fano resonance in the terahertz region. The electric dipole in the metal ring provides a bright mode, while the electric and magnetic dipoles formed in the dielectric offer bright and dark modes, respectively. Two resonance dips have been obtained with a high-quality factor of 89.5 and 23 leads to a high figure of merit of sensor equal to 6 and 4 for the first and second resonance dips, respectively, which is useful for the design and development of metamaterial-based sensing devices and biosensors. |
