摘　　要：对带机箱的共模辐射场问题采用了电场积分方程(EFIE)结合矩量法(MoM)求解。本文导体基函数采用RWG基函数,导线基函数采用脉冲基函数,连接域部分采用Costa基函数,并应用了奇异域分离法,很好地解决了连接域部分的奇异性问题。通过计算得出了几个有机箱存在时共模辐射特性的新结论。The common-mode radiation characteristic of connecting between cable and conductor is analyzed by the electric field integral function （EFIE） and the method of moment （MoM）, and that the RWG basis function is applied in the conductor basis function, the pulse basis function is applied in the wire basis function and the juncture adopt Costa basis function, and a scheme of singular region separateness is proposed to overcome the integration singularity of juncture matrix elements. Some new conclusions of the common-mode radiation characteristic when the metal case exists are obtained by numeration.
