摘要
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。
Finite-different time-domain （FDTD） method and the piecewise linear JE recursive convolution （PLJERC） algorithm for plasmas are applied for numerically simulation of one dimensional plasma photonic crystals （1D-PPC）. The electromagnetic propagation process of differential Gaussian pulse is given. The calculated band gap structure consists with the dispersive relationship derived by Kronig-Permy model. The influence of the plasma frequency, dielectric constant, the thickness ratio of plasma and dielectric material, and the periodic thickness of PPC on the band gap structure is presented.
