Polarization properties of photonic crystal tunneling mode containing single-negative materials

In order to study the polarization properties of photonic crystals containing magnetic single-negative materials, an (AB)3(BA)3 symmetrical structured one-dimensional photonic crystal was constructed from common material A(SiO2) and magnetic single-negative material B. Numerical calculation results indicate that at the normal incidence, there is a very sharp tunneling model at 1 907 nm of the original band. For TE wave, when the incident angle increases，the permittivity B or the geometry thickness variation of B medium decreases, blue-shifts are observed with the edge of band gap. The width of the tunneling mode is narrowed, the transmittance and the full-width half-maximum does not change, but its position blue shifts. When the above three parameters change respectively, the transmission spectra and the tunneling mode of TM wave change as same as TE waves. Only when the incident angle increases, the blue shift of long-wave edge of TM wave band is less than TE waves. It is helpful for designing high-quality filter.
