From: Robust high-Q filter with complete transmission by conjugated topological photonic crystals
lEl2 distribution at complete transmission resonances in 1st TES and 1st CTES. (a) lEl2 distribution at Type I. (b) lEl2 distribution at Type II*. The blue regions represent dielectric material A and the red regions represent dielectric material B, the green regions represent dielectric material C and the yellow regions represent dielectric material D, the white regions represent air. All of the parameters are the same as those used in Fig. 2, and the periodic numbers N = 10.
