   Abstract:
   This paper presents a theoretical, numerical and experimental investigation of electromagnetic wave propagation in one- and two-dimensional periodic array systems consisting of dielectric scatterers. It is shown that in certain frequency regions the waves are attenuated for all directions of propagation, and these correspond to band gaps in the calculated band structures, termed photonic band-gap (PBG) structures. A highly localized defect mode is produced by the deletion of a single scatterer from the PBG structure, for which the energy density decays exponentially. Applications of 2-D PBG structures are discussed.
