| 摘 要： | 利用时域有限差分法（FDTD）对电磁波在大气等离子体、吸波材料和金属层组合介质中传播进行二维的数值模拟。讨论了电磁波的入射角与极化模式之间的关系以及其对反射率的影响,分析了等离子体电子密度分布、等离子体层和吸波层厚度等几个重要参数对组合材料衰减特性的影响,为提高组合材料对电磁波的衰减性能提供了理论依据。

| Abstract: | The finite-difference-time-domain (FDTD) method is applied to simulate the two-dimensional propagation of an electromagnetic wave in combined media (plasma,RAM and metal layers). The simulation results indicate that the dependence of the wave attenuation on the incident angle and the polarized mode of incident wave,the electron density profile,and the widths of plasma or RAM are obtained.These results can provide the academic foundation to improve the attenuation property of the combined maedia. |
