Comparison of guided wave propagation (a) in a parallel‐plate waveguide with perfectly conducting walls and filled with either real or ideal photonic bad gap (PBG) multilayers whose unit cell comprises a positive phase velocity and a negative phase velocity layers, and (b) in the stratification direction as well as obliquely in the same PBG multilayers but of infinite transverse extent assists in the explanation of several band‐gap features and reflectance peaks, particularly those associated with zero average refractive index, computed for (a). © 2006 Wiley Periodicals, Inc.
