In this study, analysis of magnetized plasma photonic crystal (PPC) using 1-D modeling has been presented where effect of extra-ordinary modes of plasma on Photonic bandgaps (PBGs) is highlighted. The PPC characteristic has been studied in range of 1–140GHz for the different structural parameters, plasma frequency, angle of incidence, collision frequency and applied magnetic field. In the PPC, presence of static magnetic field yields the extra-ordinary mode in plasma that introduces trapped oscillations in the PBGs. This has been comprehensively analyzed and presented in detail. A procedure has been developed to identify the frequency range of the trapped oscillation in PBG. Study also explores that the trapped oscillations can be shifted at any other position in a prescribed frequency band by having suitable parameters like electronics concentration, hybrid frequency and applied magnetic field etc. Presented work can be utilized to avoid the trapped oscillation which yields non linearity in PBG.
