We perform numerical analysis of ultralarge complete photonic bandgap (CPBG) of two-dimensional photonic crystals, which are square arrays of dielectric-shell rods, with dielectric veins and intersecting veins to link them. It is shown how a maximum CPBG, Δω = 0.222592(2πc/a), is obtained within the fabrication tolerance by tuning the structural parameters. In addition, the effects on CPBG arising from the metamaterial are also discussed.
