摘　　要：用一种新的色散介质的FDTD算法称为分段线性电流密度递归卷积FDTD算法(PLCDRC)分析了非磁化等离子体的隐身技术。通过计算等离子体平板对电磁波的反射和透射系数验证了该算法的高效性和高精度。计算了电子密度Epstein分布的不均匀非磁化等离子体覆盖目标的隐身效果。A novel FDTD formulation for dispersive media called piecewise linear current density recursive convolution (PLCDRC) finite-different time-domain(FDTD) method is developed to study the stealth technology of inhomogeneous plasma in this paper.The high accuracy and efficiency of this method is confirmed by computing the reflection and transmission coefficients of electromagnetic wave through a collisional plasma slab in one dimension.The stealth effect of radar targets covered with Epstein profile inhomogeneous unmagnetized plasma is studied.
