Xiang, X. Dai, S. Wen, Z. Tang, D. Fan] A novel method to enlarge the zero-effective-phase bandgap has been presented in the one-dimensional photonic crystals by sandwiching the third material between the two single-negative materials to form a one-dimensional ternary periodic structure. The band-edges formula for the one-dimensional ternary photonic crystal is derived based on the effective-medium theory and the expressions of the upper and lower frequency limits for the ternary photonic crystals are obtained. Then two schemes to enlarge the zero-effective-phase bandgaps are put forward. Moreover, the angular- and polarization-dependences of the photonic bandgap are investigated. Finally, the role of the dispersion in the sandwiched layer on the bandgap extending has been discussed and two schemes are also presented to enlarge the zero-effective-phase photonic bandgap.
