Defect mode properties of magnetized plasma photonic crystals
磁化等离子体光子晶体缺陷态的研究

The piecewise linear current density recursive convolution (PLCDRC) finite-difference time-domain (FDTD) method for magnetized plasmas is applied to study the characteristic of one_dimensional magnetized plasma photonic crystals with a defect layer. In frequency domain, the transmission ratio of electromagnetic Gaussian pulses is computed, and the effects of periodic constant, parameters of plasma and parameters of defect layer such as dielectric length and position on defect mode properties of magnetized photonic crystals are analysed. The results show that the frequency of defect mode cannot be tuned by changing the parameters of position and periodic constant, changing the length of the defect layer can increase the number of defect mode, and the frequency and peak of defect mode can be changed by different parameters of plasma.
