Automated identification of quasi-BIC modes in disordered resonator chains using spatial field envelopes and resonance descriptors

Structural disorder turns bound states in the continuum (BICs) into quasi-BIC resonances and mixes them with spectrally close eigenmodes, so the target mode must be identified anew…
