A STATE OF THE ART REVIEW ON MODELING OF ELECTROMAGNETIC BAND GAP (EBG) STRUCTURES

Abstract

This article provides a systematic overview of the research performed in the last two decades on theoretical and computational methods of modelling electromagnetic band-gap (EBG) structures. The EBG structures have created their separate life in the antenna engineering society due to the unique features of surface wave reduction as well as perfect magnetic conductor (PMC) like action. Such devices are commonly used in the design of multiple planar microwave circuits, including printed antennas, printed microwave filters, etc. The aim of this article is to provide an inclusive analysis of both analytical and numerical approaches in the context of EBG-structure modelling. Such a review process is seldom performed to the best of the experience of writers in open literature. Researchers working on the modelling of EBG structures, as well as EBG standardized printed antennas, microwave planar filters, etc., may benefit from the review exercise.
