“…Artificial atoms (called meta-atoms) or molecules (called meta-molecules), as the basic structural elements for constructing metamaterials, are designed and fabricated to implement a device with the desired characteristics and functionalities. In particular, the meta-molecules created by engineering spatial arrangement or interatomic geometry of different types of meta-atoms achieve high-level functionalities, such as plasmon-induced transparency, multifunctional filtering, invisibility cloaking, tunable multiple resonators, reflective-index engineering, and Fano resonance [5][6][7][8][9][10][11][12][13][14][15][16][17][18].…”

Meta-molecules composed of meta-atoms exhibit various electromagnetic phenomena owing to the interaction among the resonance modes of the meta-atoms. In this study, we numerically investigated Fano-like-resonant planar metamaterials composed of meta-molecules at terahertz (THz) frequencies. We present meta-rotamers based only on the difference in the spatial position of their component meta-atoms (C- and Y-shapes) that can be interconverted by rotations and have tunable Fano-like resonance. This is because of the cooperative effects determined by the spatial coupling conditions of the nodes and antinodes of electric-dipole and inductive–capacitive (LC) resonances of the meta-atoms. The findings of this study provide potential options for exploring novel THz devices and for engineering high-level functionalities in metamaterial-based devices.
