二维任意形状金属导体的中频散射

The Intermediate-Frequency Scatter Characteristic of Arbitrary Two-dimension Conductors

本文利用保角变换方法求解出任意形状的二维金属导体的中频散射,这种方法克服了边界奇异性以及数值计算方法在处理复杂形体时难以自动控制边界点的选取以及区间自动划分的困难,利用这种方法,本文给出了对称 Joukowski 金属机翼的表面电流分布及散射截面。

In this paper,we utilize the conformal transformation method to calculate the intermediate-frequency scatter characteristic of arbitrary two-dimension conductors.in the complex boundaries,we use this method to overcome the difficulties of automati- cally choosing the points and intervals on the boundary in singular situation and nu- merical method.At the end of the paper,we apply this method to getting the distri- bution of surface current and RCS of symmetrical metal Joukowski aerofoil.
