| 摘 要： | 研究了电磁散射中的无限域问题转化为有限域的基本思想，同时给出了ＴＭ波入射时二维理想导体柱散射下闭合面上的精确第３类边界条件，并利用该条件导得的差分方程计算了数值实例．与ＭＥＩ方法进行了对比，指出ＭＥＩ方法中的第３假设值得商榷．

| Abstract: | The fundamental idea by which the problem of infinite domain may be changed to that of finite domain of Electromagnetic Scattering is studied. The exact third kind of boundary condition is given for scattering problems of the two dimensional perfect conducting cylinder under illumination by TM waves. Based on the difference equation derived by such a boundary condition, some numerical results are given. A comparison with MEI method shows that the third postulate of the MEI method is questionable. |
