Design and modelling of photonic band-gap response from doubly periodic arrays

Currently much research is aimed at using light as an information carrier in systems. Photonic crystals are materials with varying dielectric properties designed to interact with photons. If these crystals are arranged in a periodic structure they can control the propagation of electromagnetic waves through the structure. Photonic Bandgap (PBG) crystal is a periodic structure that prohibits propagation of all electromagnetic waves within a particular frequency band. Original PBG research was done in the optical region, but PBG properties are scalable and applicable to a wide range of frequencies. In recent years, there has been increasing interest in microwave and millimetre-wave applications of PBG structures. Currently, research has also extended to Metallo-Dielectric Photonic Crystal (MDPC) which is replacing the photonic crystal with periodic metal elements in low dielectric region. [Continues.]
