Abstract In this paper, photonic‐bandgap‐waveguide (PBG‐WG) structures are considered. The WGs are based entirely on linear dielectric media. Analysis is based on numerical field computation by FDTD and post‐processing of the field data. A 120° PBG‐WG bend is investigated as an example. Power transmission results are given. Various issues related to simulation arrangements and PBG‐WG component design are discussed. © 2003 Wiley Periodicals, Inc.
