对不规则金属地表面上有限长架空线受平面电磁波影响的问题提出了一个有效的解决方案 :采用复合矩量法求解不规则地表面对平面电磁波的散射 ,再针对具有分布源的架空通信传输线 ,采用解析与数值相结合的方法求解。详细地介绍了求解平面电磁波对不规则地面上架空线影响的理论分析和计算过程 ,并且针对实际工程应用的典型参数给出了计算实例并讨论了计算结果。
An effective solution of electromagnetic plane wave coupling to aerial wire over irregular conducting surface is proposed. An improved method, combined moment method, is developed to calculate the scattering field. In the procedure, transmission line theory and numerical algorithms are applied. A practical engineering example is given and conclusions and discussions are made. The method can also be utilized to solve EMI problems inside ships and airplanes.
