摘要

提出了一种新的、简单快速的求解任意形状完美导电物体的电磁散射问题的方法。该方法将导电物体表示为表面具有高阶阻抗边界条件的圆形物体。通过对覆盖物体的最小圆上的总场进行泰勒展开，得到了高阶表面阻抗与物体形状之间的普遍关系。数值模拟结果表明，该方法具有较高的精度

On the Relation between Surface Impedance and Shape of the Perfectly Conducting Objects

A new, simple and fast method for the solution of electromagnetic scattering problems related to perfectly conducting objects of arbitrary shape is presented. The method is based on the representation of the conducting object in terms of a circular one having higher order impedance boundary condition on its surface. Through the Taylor expansion of the total field on the minimum circle covering the object, a universal relation between higher order surface impedances and the shape of the object is obtained. Numerical simulations show that the method yields quite accurate results
