Abstract  The plane-wave expansion method is used to calculate the band structure of a two-dimensional photonic crystal formed by a hexagonal structure of anisotropic cylinders. Two cylindrical inclusions in the unit cell have two different radii, R1 and R2 (R1<R2). By reducing the symmetry of the structure and choosing appropriately parameters R2 and s=R1/R2 (s<1), we obtain six large complete bandgaps, among which three are over 0.05 $\omega$e (where $\omega_{\rm e}=\frac{2\pi c}{a}$) in the high region of the normalized frequency (however, one of these over 0.065 $\omega$e is not stable). There are two other stable complete bandgaps in the low-frequency region.
Keywords:  complete bandgap      hexagonal structure      symmetry      stability
