本文提出一种ＭｏＭ－ＣＧＭ－ＦＦＴ（矩量法－共轭梯度法－快速富立叶变换）的混合技术来分析任意截面和非均匀介质柱的做射问题。该方法是以等效电流作为未知函数进行求解。该方法适应世广，是一种求解电磁散射问题的简单途径。由于应用了ＣＧＭ－ＦＦＴ技术，降低了所需计算机内存和ＣＰＵ时间，可以有效地处理电子尺寸的柱体散射和非均匀介质柱的散射，本文给出的数据和准确结果相比较，吻合好。
In this paper, a hybrid MoM-CGM-FFT (MoM-conjugate gradient method-fast Fourier transform) hybrid technique is proposed to analyze the projectile incidence of arbitrary cross-section and inhomogeneous column. The method is based on the equivalent current as an unknown function. The method adapted to World Wide, is a simple way to solve the problem of electromagnetic scattering. Due to the application of CGM-FFT technology, the required computer memory and CPU time are reduced, which can effectively deal with the electron-size cylinder scattering and the dispersion of the non-uniform dielectric column. The data given in this paper is in good agreement with the accurate results.
