| 摘 要： | 基于严格的电磁场理论,文章分析了正负双层介质涂覆金属柱的电磁散射特性,并讨论了金属柱包层厚度对远区散射场的影响.通过分析单层正介质和双层介质涂覆下金属柱的电磁散射特性,可知适当选取外层双负介质厚度能有效降低金属柱的后向散射场.

| Abstract: | Based on the rigorous electromagnetic theory,the electromagnetic scattering characteristics of a conductor cylinder coated with two-layer positive and negative materials is analyzed.The effect of the thickness of each material on the far scattering field is also discussed.By analyzing the electromagnetic scattering characteristics of the conductor cylinder coated with one-layer positive material and two-layer materials,it is concluded that the radar backward cross section can be reduced effectively if the t... |
