Off-plane band structure for triangular and square lattice with non-zero kz component were calculated using Plane Wave Expansion Method. Both decreasing, finally breaking down of in-plane band gaps and emerging of new off-plane band gaps were observed with an increasing kz. Kz component dependence of band gap was investigated in both triangular and square lattice, with varied air hole radius and dielectric constant.
