Abstract
In this study, we propose polarization dependent resonance manipulation by meta-molecules at terahertz frequencies. The proposed meta-molecules are combined with various numbers of H-shaped meta-atoms, which we refer as ‘moleculization’ of meta-atoms. We confirm that the laterally moleculized H-shaped meta-molecules successfully realize the unique properties that can modulate the resonance frequency for the specific polarization of an incident wave, while can keep one identical resonance frequency for their orthogonal polarization direction, simultaneously. Moreover, for the vertically moleculized H-shaped meta-molecules, we also find that the electromagnetically induced transparency (EIT) –like phenomenon can be achieved for the specific polarization direction, with their exceptional field enhancement properties.
