Onedimensional traditional pure dielectric photonic crystals have disadvantages that the design of TEpolarization bandpass filters is difficult, and the bandgaps of TE and TMpolarization bandpass filters are narrow. Based on the fact that a greater permittivity (permeability) than permeability (permittivity) makes wider TE (TM) bands than TM (TE) bands, three kinds of filters, (TEpolarization bandpass filter, TMpolarization bandpass filter and doublepolarization bandpass filter), were designed by stopband superposition of onedimensional photonic crystals. Each of them was a heterostructure constructed by two subphotoniccrystals, hence the structure provided a narrowfrequency passband and the bandgap was enlarged. Due to the combination of dielectric and magnetic materials, the proposed design has simple structures with wide bandgaps and narrowfrequency passbands. Besides, the effect of magnetic material dispersion on the performance of polarization filters was discussed using a kind of magnetic material which has been reported.
