RCS of 2-D target loaded with anisotropic magnetized plasma computed by FDTD
用FDTD计算各向异性磁化等离子体涂敷二维目标的RCS

The finite-difference time-domain(FDTD) method is extended to two dimensional anisotropic dispersive media-magnetized-plasma using Z transformation for the f ist time. The problem which incorporates both anisotropy and frequency dispersio n at the same time is solved for the electromagnetic wave propagation. The two d imensional FDTD formulations for anisotropic magnetized plasma are derived. The method is applied to the electromagnetic scattering of perfectly conducting cyli nder coated with anisotropic magnetized plasma. By simulating the interaction of electromagnetic wave with magnetized plasma, some bistatic numerical results ar e obtained, which indicate that an appropriate plasma coating may efficiently re duce the RCS of a metallic target.
