摘要

本文研究了等离子体与电磁波的相互作用。结果表明，高反射系数要求低碰撞频率和高等离子体密度。在密度过大的情况下，非磁化无碰撞冷等离子体与金属导体的散射特性可比较。以等离子体球为例，给出了满足RCS要求的等离子体球参数。讨论了等离子体在大空间尺度下的散射特性。

Numerical research on the RCS of plasma

In this paper, the interaction between plasma and electromagnetic waves is studied. It demonstrates that high reflection coefficient requires low collision frequency and high plasma density. If its density is overdensed, the scattering characteristics of nonmagnetized collisionless cold plasma and metal conductor are comparable. As an example, the parameters of a plasma sphere with required RCS is given. The scattering characteristics of plasma with a large space scale are also discussed.
