| 摘 要： | 该文计算和分析了平面波垂直照射下，导电圆柱及其覆盖有耗介质后的ＲＣＳ。提出了导电圆柱及其覆盖有耗介质后，爬行波电流传播常数以及幅度的数值计算方法，该方法不仅克服了低频时，几何绕射法对导电圆柱表面爬行波传播常数计算精度差的缺陷，而且解决了几何绕射法难以求解的有耗介质包层的导电圆柱表面爬行波电流传播常数的数值计算，特别是解决了爬行波电流模的幅度计算问题。

| Abstract: | The ROS of a lossy material coated conducting cylinder has been computed and analysed, and a numerical method for computing creeping wave propagation constants and amplitudes on the surface of the cylinder is presented in the paper. On the surface of a conducting cylinder,the defect of low precision for creeping wave propagation constants obtained by Keller's formulas at low frequency is overcome by the method. Propagation constants and amplitudes of creeping wave current modes on the surface of a lossy material coated conducting cylinder.which are hardly obtained by GTD, have been resolved. |
