采用非磁化等离子体的分段线形电流密度卷积(Current density convolution,JEC)时域有限差分(Finite-dif-ferent time-domain,FDTD)算法研究了具有单一缺陷层的一维时变非磁化等离子体光子晶体的缺陷模特性。以高斯脉冲为激励源,通过由算法公式得到的电磁波透射系数讨论了等离子体上升时间对其缺陷模的影响。结果表明,改变等离子体的上升时间和密度可以获得不同的缺陷模。 A one-dimensional time-varying non-magnetization with a single defect layer was studied by using the non-magnetized plasma-based piecewise linear density current density convolution (JEC) Finite-Dif-ferent time- Defect mode properties of plasma photonic crystals. Using Gaussian pulse as excitation source, the influence of plasma rise time on the defect modes was discussed by the electromagnetic wave transmission coefficient obtained from the algorithm formula. The results show that different defect modes can be obtained by changing the plasma rise time and density.
