| 摘 要： | 为分析闭式等离子体用于飞行器隐身的可行性,引入了可观隐身效果的概念及对应的闭式等离子体厚度。采用WKB方法,详细研究了X波段下的闭式等离子体吸波效果,得到了对应频段下产生可观隐身效果需要的等离子体厚度;研究了不同电子密度分布的吸波特性,数值算例说明,对不同电子密度分布的等离子体,吸波效果与厚度均成线性关系,同时,采用理论推导验证了该现象的正确性。结果表明,对于给定的电磁波,采用一定厚度的闭式等离子体可以达到可观隐身效果。

| Abstract: | To analyze the feasibility of closed plasma used on the stealth aircraft,this paper presents a novel concept and corresponding closed plasma thickness.The absorption effect of closed plasma on X band is researched in detail by using WKB method,and the closed plasma thickness needed to produce the considerable stealth effect is obtained.This paper investigates absorbing characteristics of the different plasma electron density distributions,which is demonstrated to be a linear relationship between absorption ... |
