摘要: 本文应用Minkowski变换研究了轴向运动非均匀等离子柱体的电磁散射。表明在坐标变换中易于导出相应稳态问题的解。文中详细研究了一半径为1m的等离子柱体的一些散射远场特性,其中包括远场方向图和后向散射横截面积(RCS)。

Abstract: Scattering of electromagnetic waves by a inhomogeneous plasma column-moving uniformly in the axial direction is studied by means of Minkowski transformation. It shows that the solution of the stationary problem is derived readily in transformation coordinates. Several important characteristics of the scattered farfields are investigated in detail for, a cylinder of radius equal to 1m. This includes the calculation of farfield patterns and radar scattering section (RCS).

Key words: special theory of relativity, plasma column, electromagnetic scattering.
