| 摘 要： | 导出了低频时谐电磁场中均匀半空间导体的并矢格林函数解析式,它由初等函数和修正贝塞尔函数的有限形状所表示．该解析式可用Kelvin函数的近似多项式计算,可显著提高并矢格林函数的计算速度．用"电磁分析方法验证模型"的第15号问题作为验证模型,结果表明,计算值和测量值吻合良好．

| Abstract: | In thes paper, an analyhcal formula of dyadic Green's function is presented for homogenoous half-space conductor in low frequency time harmonic tarnagnetic field.It is expresed in the finite forms of thetary functions and modified Besse functions. It can be calculatal using the approximated polynondals of Kevin functions. Through this analytical formula, dyadc Gree's fundion can be calculatal effidenhy. As an example the TEAM hang Electromagnedc Analysis Methods) Workshop Problem No.15 was caiculated.The caculated results are in good agreement with its experimental results. |
