| 摘 要： | 采用磁化等离子体的分段线形电流密度卷积(Piecewise Linear Current Density Recursive Convolution,PLCDRC)时域有限差分(Finite-Different Time-Domain, FDTD)算法研究了一维时变磁化等离子体光子晶体的禁带特性。以高斯脉冲为激励源,用算法公式所得的电磁波透射系数来讨论了等离子体上升时间、密度、周期常数对其禁带特性的影响。结果表明,改变等离子体上升时间和密度可以实现对禁带的控制。

| Abstract: | The piecewise linear current density recursive convolution(PLCDRC) finite-different time-domain(FDTD) method for magnetized plasmas was applied to study the characteristics of the one dimension time-varying magnetized plasma photonic crystal forbidden band gaps.The electromagnetic propagation process of a Gaussian pulse through a time-varying magnetized plasma photonic crystal was investigated.The transmission coefficients through time-varying magnetized plasma photonic crystals were calculated,and the effe... |
