摘要
磁化等离子体光子晶体是磁化等离子体和介质(真空)构成的人工周期性结构.本文用磁化等离子体的分段线形电流密度卷积(PLCDRC)时域有限差分(FDTD)算法分析了磁化等离子体光子晶体特性.分析了磁化等离子体参数对电磁带隙的影响.从时域的角度分析了高斯脉冲在磁化等离子体光子晶体中的传播过程,给出了时域反射和透射波形.从频域的角度给出了磁化等离子体光子晶体的电磁反射系数和透射系数,并对结果进行了分析.
Magnetized plasma photonic crystals are artificial periodic structures composed of magnetized plasmas and dielectric structures (or vacuum). In this paper, the piecewise linear current density recursive convolution (PLCDRC) finite-difference time-domain (FDTD) method for magnetized plasmas is applied to study the magnetized plasma photonic crystals. The effect of parameters of magnetized plasma on electromagnetic band gap is presented. In time-domain, the electromagnetic propagation process and reflection/transmission electric field of Gaussian pulses through magnetized plasma photonic crystals are investigated. In frequency-domain, the reflection and transmission coefficients through magnetized plasma photonic crystals are computed. The results are discussed.
