infrared millimeter terahertz waves scientific conferences

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.
