A broad complete photonic band_gap (larger than 18%) in compound square lattices, and both single and double absolute band gaps in compound triangular lattices are obtained by optimization of the structure parameter. The relationship curves between absolute band gaps and the structure parameter are demonstrated. The simulation results also show that the shifts of two sub_lattices affect the band_gap a little.
