摘　　要：表面离散化边界方程法是最近被提出的分析电磁散射问题的数值方法,论文基于组合场积分方程的表面离散边界方程法,分析了二维导体的电磁散射问题.数值计算结果表明:对于TM波,基于组合场积分方程的表面离散化方程与基于电场积分方程的表面离散边界方程法的精度和收敛速度相当,然而对于TE波,前者则具有更高精度和更快的收敛速度.On-surface Discreted Boundary Equation（OS-DBE） was a newly developed numerical method for electromagnetic scattering problems, to completing the scattering analysis of two dimensional conductive objects, the OS-DBE based on combined field integral equation was presented for and the numerical experiments demonstrated that the precision and convergence were agree well with the OS-DBE based on electric field integral equation for transverse magnetic wave, however, the accuracy and convergence were improved for transverse electric wave.
