EM characterization of photonic band gap (PBG) structures: an overview

Summary form only given. Most previous studies of PBG structures were directed towards design and experimental performance evaluation. Attention has also focused on EM theoretical/numerical modeling and performance characterization of these complex structures. An overview of the application of modern numerical techniques is presented. Among these techniques special emphasis is given to the application of FDTD and periodic method of moments. The performance of several candidate PBG structures is evaluated to critically examine the EM properties of PBGs and their potential utilization in various applications. Attempts are made to provide physical and engineering insights into PBGs in the microwave and millimeter wave regime.
