Achieving asymmetry parameter-insensitive resonant modes through relative shift–induced quasi-bound states in the continuum
High-Q resonances in metasurfaces, stemming from symmetry-protected bound states in the continuum (BICs), have proven to be effective for achieving high-performance optical devices. However, the properties associated with symmetry-protected BICs are inherently limited, as even a slight variation in...
