摘要 采用z变换方法把FDTD推广应用于二维各向异性色散介质—磁化等离子体中,该算法同时解决了电磁波在各向异性和频率色散介质中传播的问题,给出了各向异性磁化等离子体中FDTD迭代公式。计算了各向异性磁化等离子体涂敷Von Karman型导体柱前后其单站RCS的变化情况,分析了等离子体参数对其RCS的影响。结果表明恰当地选择等离子体参数能有效地减少目标的RCS。 The finite-difference time-domain（FDTD） method is extended to two dimensional anisotropic dispersive media-magnetized plasma by using z transformation. This leads to the electromagnetic wave propagation of both anisotropy and frequency dispersion media can be solved at the same time. The two dimensional FDTD update formulations for anisotropic magnetized plasma are presented in this paper.. For the electromagnetic scattering of Von Karman shaped conducting cylinder coated with anisotropic magnetized plasma, the effect of the plasma parameters on the backscattering cross section is investigated and some monostatic numerical results are obtained. The results indicate that an appropriate plasma coating may efficiently reduce the RCS of a metallic target.
