(a) The plot of logarithm base 10 of transmittivity spectrum, \({\textrm{log}}_{10}T\), as a function of non-Hermitian degree. (b) Dispersion relation of defect modes. (c–e): Plots of logarithm base 10 of generalized decay rate modulus \({\textrm{log}}_{10}\left| \gamma \right| \), the phase difference \(\delta /\pi \), logarithm base 10 of quality factor \({\textrm{log}}_{10}\left| Q\right| \), as functions of non-Hermitian degree. (f) Electric field amplitude distribution of defect modes at different non-Hermitian degrees. Each plot uses parameters identical to those in Fig. 3, except for the parameter being studied in that specific plot.
