摘　　要：利用基于拉氏变换的电流密度卷积(LT-JEC)时域有限差分(FDTD)方法处理等离子体复杂介质;同时通过引入周期边界条件,将无限大周期结构转换为单个元胞的有限区域的计算,实现了抽象模型向实际计算模型的转变,计算了以等离子为背景的二维等离子光子晶体的功率反射和透射系数。研究了二维等离子体光子晶体带隙特性随等离子体各参数变化的变化规律,为实际制作等离子体光子晶体提供了理论基础。The Laplace Transfer-current density convolution （LT-JEC） finite difference time-domain （FDTD） method is used to deal with the complex magnetized plasma. By using the periodic boundary condition, the abstract model transfers into the practical model which can be calculated by FDTD. The plasma photonic crystals consist of the media embedding in the plasma . The algorithm is applied to calculate their power reflection and transmission coefficients of the different plasma parameters, and some useful conclusions are obtained. This work provides theory basis to make the practical plasma photonic crystals.
