Anisotropy modeling of polarization dependent terahertz metamaterials
Hyunseung Jung and Hojin Lee
Abstract
We propose a novel anisotropy modeling of the polarization dependent meta-atoms at terahertz frequencies. The proposed anisotropic metamaterials are composed of metallic microstructures combined with various numbers of H-shaped meta-atoms. We confirm that the proposed metamaterials 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, regardless of the number of H-shaped meta-atoms as well as the polarization direction, their bandwidth can be kept identical by coupling effects between adjacent meta-atoms and their excited electric dipole moments.
