4. Photonic crystals of finite size and periodicity defects

The study of photonic bands, carried out in paragraph 3 , assumes the periodic crystal to infinity, whereas real crystals are obviously of finite size. Moreover, reducing studies of 1D and 2D crystals to one and two dimensions, respectively, is also a simplistic approach, since light can propagate off-axis in 1D crystals just as it can propagate off-plane in 2D crystals. In short, light diffraction in all...
