摘要： 该文提出了将爬行波电流本征函数级数解与Prony方法相结合,提取导电圆柱有耗介质包层表面爬行波电流模及其幅度的新方法。该方法不仅解决了爬行波电流模传播常数的数值计算,而且还解决了爬行波电流模的幅度计算。

Abstract: A new method for computing propagation constan ts kn and amplitudes an of creeping wave-modes in the lossy matrial is preseated in the paper. Tbe method combines eigenfuaction solutions of creeping wave currents with Prony method and solves the numerical computation of kn, an. For the losses material, propagation constants obtained by the method are in good agreement with those in reference[3].
