摘要

在镜像对称的超表面上，通过引入不对称参数α，得到局部反演对称支持的理想BIC转化为QBIC。在Q∝α - 1.95之后，这种跃迁产生一个有限的Q因子，而奇异偏振态分裂成两个不同的圆偏振点。该框架确保了Γ-point处强大的BIC形成，即使在空间晶格位移下也能保持高性能。

Robust Bound States in the Continuum in Mirror-Symmetric Terahertz Metasurfaces

An ideal BIC, supported by local inversion symmetry in a mirror-symmetric metasurface, transforms into a QBIC by introducing an asymmetry parameter α. This transition yields a finite Q-factor following Q ∝ α−1.95, whereas the singular polarization state splits into two distinct circularly polarized points. This framework ensures robust BIC formation at the Γ-point, maintaining high performance even under spatial lattice displacements.
