Abstract
In this paper, multichannel filter tunability containing magnetized plasma and anisotropic metamaterial in 1D ternary photonic crystal is theoretically investigated and designed at 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 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, optical axis angle of anisotropic metamaterial and incident angle on the filter properties of channels for both TE and TM polarization is investigated.
