The photonic band structures of two-dimensional square compound lattices are calculated by the plane-wave method. Four air hole cylinders drilled in a square dielectric cylinder which locate at each square lattice site are embedded in a background of air. Three absolute photonic band gaps common to E and H polarized waves are created when given proper structure parameters.
