Generalized Fano lineshapes calculation. a The difference between the profiles obtained by the waveguide and near-field models, for κ = 0.8κ₀ and γ₁/γ₂ = 10, as reported in Fig. 1b and e, gives rise to a Lorentzian dip corresponding to the transmission of the waveguide coupled to a single-cavity system. The near-field generalized Fano profile (central red line) is reproduced by Eq. (1) (blue line) with the fit output parameter q = −1. b Four representative generalized Fano lineshapes obtained by the near-field model using Supplementary Eq. (61) close to the EP. They show 0, 1, 2, and 3 zero-crossing with the zero-value baseline, respectively
