摘要

An analog of electromagnetically induced transparency (EIT) in plasmonic double disk resonators aperture-side-coupled to an InSb bus waveguide at the terahertz (THz) frequency region has been investigated. When there is a destructive interference coupling between these two disk resonators, the proposed plasmonic structure exhibits a transparency window. The simulation results show that the EIT-like response is dependent on the coupling distance between two disk resonators. Since the permittivity of InSb is modified by varying temperature, the central wavelength of the EIT-like transmission can be controlled by tuning the temperature. The proposed plasmonic structure may have applications in THz integrated circuits.
