Comment on "Photonic Band Gaps: Noncommuting Limits and the 'Acoustic Band'"
Abstract
This Comment concerns the effective dielectric constant for 2D photonic crystal. We show that even in the limit of very high dielectric constant of photonic crystal's "atoms", static and quasistatic approaches give the same results, unlike it was claimed by Nicorovichi et al, PRL, 75, 1507 (1995).
