| dc.description.abstract | The rotational invariance of the effective refractive index in the 2-D photonic crystal is discussed. It is proven that, in the case of the n-fold symmetrical omega-k equifrequency surface (EFS), there are two solutions that show the invariance of the effective refractive index after rotating a multiple of the basic repeated angle 2 pi/n within the first Brillouin zone. For the noncircular solution, the behavior of the effective refractive index N-eff(theta) at normal incidence shows that N-eff(0 degrees) has an additional constant of two in the very high symmetric EFS, higher than in the low symmetric case. | en_US |
