(a) Type I: Band structure and Zak phases of PC 1, (b) Type I: Band structure and Zak phases of PC 2 (c) Type I: transmission spectrum of PC 1 and PC 2. (d) Type II*: Band structure and Zak phases of PC 1, (e) Type II*: Band structure and Zak phases of PC 3 (f) Type II*: transmission spectrum of PC 1 and PC 3. Type I: the parameters of the considered structure are nA = 3, nB = 1, nC = 3, nD = 1, ni = no = 1, F1 = 0.3, F2 = 0.38. Type II*: the parameters of considered structure are nA = 3, nB = 1, nC = 1, nD = 3, ni = no =1, F1 = 0.3, F3 = 0.7.
