## Abstract This paper shows that inside photonic band gap (PBG) materials the effective index of refraction __n__~__eff__~, defined in terms of group velocity, becomes negative in a certain range of frequencies. Also, near the photonic‐band edge the effective index of refraction __n__~__eff__~ att
