Abstract-Mode coupling in terahertz metamaterials using sub-radiative and super-radiative resonators
We theoretically and experimentally explored the electromagnetically induced transparency (EIT) mode-coupling in terahertz (THz) in which a dipole with a super-radiative mode is coupled to an inductance-capacitance with a sub-radiative mode. The interference between these two depends on the relative spacing between them, resulting in a tunable transparency window in the Mode coupling was experimentally demonstrated for three spacing dependent EIT Transmittance of the transparency windows could be either enhanced or suppressed, producing different spectral linewidths. These spacing dependent mode-coupling provide alternative ways to create THz devices, such as filters, absorbers, modulators, sensors, and slow-light devices.
