Abstract

A Finite Difference Time Domain (FDTD) analysis has been effectively applied to investigate the transmission of the transverse electric polarized pulses in photonic crystals arrangements. The photonic bandgap of 2-D photonic crystal with square and veins lattices has been calculated using three methods Band structure, transmission diagram and defected structures, and comparison with published results are done and excellent agreement are obtained, Moreover, two different photonic crystal devices are analyzed Index Terms: Photonic Crystal [PC], Finite Difference Time Domain (FDTD), Photonic Bandgap (PBG).
