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)算法研究了具有单一缺陷层一维时变磁化等离子体光子晶体的光子局域态特性。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对其缺陷模的影响。结果表明,改变等离子体上升时间和密度可以获得不同的缺陷模。
A one-dimensional time-varying magnetized plasma with a single defect layer was studied by using Piecewise Linear Current Density Recursive Convolution (PLCDRC) Finite-Difference Time-Domain (FDTD) PHOTONIC LUMINESCENCE PROPERTIES OF PHOTONIC CRYSTALS. Taking the Gaussian pulse as the excitation source, the influence of plasma rise time on the defect mode is discussed with the electromagnetic wave transmission coefficient obtained by the algorithm formula. The results show that different defect modes can be obtained by changing the plasma rise time and density.
