BIC-supporting metasurfaces can achieve the high-Q resonance. The Q factor can be controlled by changing the size of the introduced defect and further this relationship can be adjusted by the proposed design (bottom left). By optimizing the dimensions of the structures, a high-Q resonance can be easily achieved and the THG signal can be enhanced significantly.
