Abstract
In this paper, the tunability of a multichannel filter containing magnetized plasma and anisotropic metamaterial in 1D ternary photonic crystal is theoretically investigated and designed in the GHz frequency range. The results show that resonance modes in transmission spectrum of the proposed structure without defining defect layer are created and the structure with a ternary periodicity can act as the multichannel filter. The tunability of the transmission spectrum of the proposed structure by applying an external magnetic field is investigated and shown that channels frequency can be red or blue shifted depending on the orientation of external magnetic field. In addition, the effect of the number of periodicities, the optical axis angle of the anisotropic metamaterial and the incident angle on the filter properties of the channels for both TE and TM polarization is investigated
