采用时域有限差分方法(FDTD),结合等离子体计算中的分段线性电流密度卷积技术(PLJERC)对一维等离子体光子晶体(1D-PPC)进行了数值模拟,给出了微分高斯脉冲在一维等离子体光子晶体中的传播过程。计算得到的带隙结构与K-P模型方法的结果一致。计算并分析了等离子体频率、介质介电常数、等离子体-介质层的厚度比以及周期厚度对一维等离子体光子晶体带隙结构的影响。
A one-dimensional plasma photonic crystal (1D-PPC) was numerically simulated by FDTD combined with piecewise linear current density convolution (PLJERC) in plasma calculations. The differential Gaussian pulse Propagation in one-dimensional plasma photonic crystals. The calculated bandgap structure is consistent with the K-P model method. The effects of plasma frequency, dielectric permittivity, thickness ratio of plasma-dielectric layer and cycle thickness on the band gap structure of one-dimensional plasma photonic crystal were calculated and analyzed.
