求解电磁场边界问题时逆规则的物理意义

The physical meaning of the inverse rule when solving the boundary-problem of the electromagnetic field

本文在分析Laurent’s规则应用于光栅理论时产生慢收敛的原因的基础上 ,首次提出了用于解决这种慢收敛问题的逆规则的物理意义 ,并应用实例对逆规则的物理意义进行了详细的阐述 。

On the base of analyzing the reason of slow convergence caused by applying the Laurent's rule to the grating theory,the paper firstly brings forward the physical meaning of the inverse rule which is used to solve this kind of slow convergence and uses actual example to expound the physical meaning of the inverse rule in detail so as to make readers have a profounder comprehension of the important theory in the physic field.
