The black circles represent the simulated results obtained through the transfer matrix method, while the red lines and dots correspond to the predictions from our generalized temporal coupled-mode theory. The transmittivity spectrum and the reflectivity spectra for left and right incidences are plotted in (a), (b), and (c), respectively. The phase of the transmission coefficient and the reflection coefficients for left and right incidences are displayed in (d), (e), and (f), respectively. The parameters employed in the fitting theory are as follows: \(x=3.1944\), \(\varphi =-0.8433\pi \), \({\omega _0\Lambda }/{2\pi c}=1.5184\), \({\gamma \Lambda }/{2\pi c}=-4.4520\times {10}^{-7}\), and \(\delta =0.5669\pi \). The remaining parameters of the model remain consistent with those in Fig. 2, and the chosen number of unit cells here is \(N=6\).
