摘要

本文提出了一种计算金属圆柱表面爬行波电流传播常数和幅度的新方法．该方法在获得金属圆柱表面爬行波电流的精确数值解后，应用Ｐｒｏｎｙ方法求得了金属表面爬行波电流各个模的传播常数和幅度，避开了传统方法求解时冗长、繁锁的数学推导过程．经比较，本文方法的计算结果比几何绕射理论的计算结果更为精确．

Abstract

A new method for computing propagation constants and amplitudes of creeping wave modes on an infinite conducting circular cylinder is presented. After acquired creeping wave currents on the surface of circular cylinder by its eigenfunction series

propagation constants and amplitudes of creeping wave current modes are obtainted by applying Prony’s method and complicated derivation is avoided. Numerical results obtained by applying Prony’s method are more accurate than those obtained by Keller’s formulas.
