## 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

## Abstract In the paper of Ojha et al. (Microwave Opt Technol Lett 42 (2004), 82–87), an erroneous definition of the effective refractive index __n__~__eff__~ in a photonic band gap (PBG) structure is used. The effective refractive index __n__~__eff__~ is defined as a function of the group velocit
