The piecewise linear current density recursive convolution (PLCDRC) finite-different time-domain (FDTD) method for magnetized plasmas was applied to study the characteristic of defect mode for one dimension magnetized plasma photonic crystals with a defect layer under the isothermal hypothesis. The electromagnetic propagation process of a Gaussian pulse through a magnetized plasma photonic crystal was investigated. The transmission coefficients through magnetized plasma photonic crystals were calculated, the effects of plasma temperature and density on characteristics of defect modes for magnetized plasma photonic crystals were analyzed with them. The results illustrated that the different defect modes can be obtained by changing plasma temperature and density.
