摘要

本文引入一种数值吸收边界条件

将其应用于解决开放空间电磁散射问题的表面辐射条件法（OSRC）之中。本文使用这种边界条件对理想导电及均匀电磁可穿透材料圆柱散射体的表面场进行了数值计算

并与使用二阶微分算子B

型的吸收边界条件的结果作了比较。所有结果说明

这种数值吸收边界条件特大大改善OSRC方法的精度。

Abstract

In this paper a numerically derived absorbing boundary condition has been introduced to apply to the on-surface radiation condition （OSRC） method for the solution of open region scattering problems.Numerical results for perfectly conduction and homogeneous penetrable circular cylinder are presented and compared with the solutions by using second-order differential operator B2 type absorbing boundary condition.It is shown that the accuracy of OSRC method can be significantly Improved by using this kind of numerical absorbing boundary condition.
