Description: The dispersion relation and the optical transmittance of a two-dimensional photonic crystal composed of the
hexagonal array of cylindrical air holes fabricated in a dielectric slab were analyzed by group theory and the
numerical calculation based on the fi nite-difference time-domain method. The decay rate of the leaky modes
that exist above the light line ~the dispersion relation in air! in the band diagram was also evaluated, from
which the absence of the coupling between certain internal eigenmodes and the external radiation fi eld was
shown. This phenomenon was related to symmetry mismatching by the group-theoretical argument.
