摘要
该文分析了自由空间中平面波激励下各向异性两层圆柱的二维电磁散射特性。在各向异性媒质波函数理论的基础上,求出均匀各向异性媒质圆柱各区域内的电磁场的解,该解是由一系列本征函数累加求和得到的。利用电场和磁场在介质表面的连续性建立边界方程,从而求出散射参数,最后再根据求得的散射参数求出各向异性两层圆柱的雷达散射截面。
This paper presents the two-dimensional scattering characteristic of a anisotropic circular cylinder inspired with plane wave electromagnetic in free space.On the basis of the anisotropic circular cylinder wavefunctions,we can obtain the expressions of the electromagnetic which is composed with series eigenfunctions in every areas.Then using boundary conditions of the electromagnetic, we can obtain scattering coefficient by which can get bistatic radar cross sections.
