摘要： 用一种新的色散介质的FDTD算法——分段线性电流密度递归卷积FDTD算法分析了不均匀等离子体的隐身技术.通过计算一维碰撞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.对电子密度抛物线分布的不均匀非磁化等离子体覆盖雷达目标的隐身效果进行了时域和频域分析.

关键词: 色散介质, 等离子体隐身, FDTD算法, 电磁波

Abstract: In this paper a novel FDTD formulation for dispersive media called piecewise linear JE recursive convolution (PLJERC) finite-different time-domain (FDTD) method is used to study the stealth technology of inhomogeneous plasma. 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 parabolic profile inhomogeneous plasma is studied both in time-domain and frequency-domain.

Key words: FDTD methods, dispersive media, electromagnetic wave, plasma stealth
