Abstract

Guided wave propagation in a circular waveguide filled with dielectric materials in the Kronig-Penney morphology is theoretically examined. Allowed and forbidden frequency bands in these ideal photonic band-gap (PBG) structures are obtained for the TEz and TM2 propagation modes by invoking the Bloch theorem. Results show the many engineering possibilities for designing electromagnetic filters for ideal structures. Filtering by real PBG structures with a finite number of unit cells is also studied by using the scattering matrix technique. As the number of unit cells in a real filter increases, its transmission characteristics converge to those of its ideal analog in the forbidden frequency bands.
