%X Constant-frequency contours analysis method and the plane-wave method were employed to gain the frequency range of the incident electromagnetic waves when all-angle negative refraction (AANR) phenomenon occurs in two-dimensional photonic crystals.The dependence of the frequency range on structural paramerter (crystal lattice shape, the ratio of the rod radius and the lattice constant) and electromagnetic parameter (the dielectric constants of the rods and of the background, incident electromagnetic waves with different polarization) were investigated. The result shows that when a dielectric constant is fixed, it is necessary that the other dielectric constant reach a threshold. Photonic crystal has its optimized structural parameter and electromagnetic patameter when it has its largest AANR freqency range.
