Abstract The dispersion characteristics and phase index of electromagnetic waves in two types of magnetized one dimensional ferrite photonic crystals with mixed field configuration are studied for transverse magnetic mode. The dispersion equation and formula for phase index are derived using transfer matrix method. It is found that in type-1 & type-2 magnetized one dimensional ferrite photonic crystals, photonic band gaps (PBGs) show dependence on HOYIG and HONI respectively. The PBGs corresponding to thinner YIG layer are at higher frequency side at fixed. The variation of frequency-filling factor shows that PBGs occur in the form of lobe for both types. It is observed that the phase index is strongly influenced by external magnetic fields, and filling factor. It is demonstrated that PBGs in phase index occur in the form of lobes at fixed. Also, with decrease in the magnitude of phase index, number of lobe increases. The phase index, field and frequency plots show that there are multiple peaks in the PBGs of phase index in the lower frequency.

Reflection And Transmission Coefficient

Applying transfer matrix method, we get reflection and transmission coefficient of finite one dimensional photonic crystals. At the same time, we consider the position influence of single defect. We find the frequency of defect mode is same, but the height of transmission peak is not same when single defect is in different position of crystal. The transmission peak is maximum when the defect is in center of finite one dimensional photonic crystals.
