ABSTRACT Generating pre‐designed vectorial beams via on‐chip devices can yield many fascinating applications, but traditional diffraction‐based devices are bulky and inefficient. While plasmonic metasurfaces exhibit ultra‐compact sizes and deep‐subwavelength resolutions, their working efficiencies are limited by metallic losses.

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
