摘要

提出了一种改进的表面离散边界方程(OS-DBE)方法，用于求解具有电大凹部的导电圆柱体的散射问题。它利用原始OS-DBE逐点确定凸部表面电流密度，而通过OS-DBE只需一次操作即可获得凹部的电流分布。数值结果验证了该方法的有效性。

Modified on-surface discretized boundary equation method for solving scattering problems of concave conducting cylinders

A modified on-surface discretized boundary equation (OS-DBE) method is proposed for solving scattering problems of conducting cylinders with electrically large concave parts. It utilizes the original OS-DBE to determine the surface current density on the convex part point by point, while obtains the current distribution for the concave area by the OS-DBE in only one operation. Numerical results are presented to demonstrate the validity of the proposed approach.
