Owing to strong light confinement ability, the optical resonators are of great interest to the scientific community,
however, their optical performances are often limited by the outof-plane scattering caused by fabrication defects. A physical mechanism known as the Bound States in the Continuum (BIC), can suppress the scattering loss that could lead to improved optical devices. Utilizing the BIC effect, we propose a standard metasurface that can achieve an ultra-high Q factor of 6302. To our knowledge, the achieved Q-factor is the highest achieved by
terahertz metasurface so far.
