Abstract: In order to study transmission property of 1-D ternary magnetized plasma photonic crystals,the transfer matrix method was applied to get the transmission characteristics for TE wave,divided into left-handed and right-handed circularly polarized waves after propagating through 1-D ternary magnetized plasma photonic crystals.The calculated transmission coefficients were used to analyze the effect of periodic constant,dielectric constant,thickness of dielectric layers and parameter of plasma on the transmission characteristics.The results illustrate that the numbers and width of band gaps can be tuned by changing dielectric constant,thickness of dielectric layer and plasma frequency,the width of band gaps can not be affected by increasing periodic and plasma collision frequency.The band gaps for right-handed circularly polarized wave can be tuned by the plasma gyro frequency,but band gaps for the left-handed circularly polarized wave can't.The results are good theoretical references to design 1-D ternary magnetized plasma photonic crystal devices.
