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.

Using the transfer matrix method, absorbing properties of electromagnetic waves in one-dimensional plasma photonic crystals are proposed. Compared with the absorption of bulk plasma, more absorbing bands have been found in one-dimensional plasma photonic crystals, and the first absorbing band appears below the plasma frequency. These absorbing bands can be controlled by varying structure parameters, plasma parameters and the incident angle. Results show that the periodic number and collision frequency only control the absorbing magnitude. Plasma frequency, plasma thickness and incident angle affect both the absorbing magnitude and locations. Increasing the dielectric constant of the dielectric makes more absorbing bands appear. These features of one-dimensional plasma photonic crystals would have potential applications in tunable millimetre absorbers.
