摄动法在电磁场分析中的应用研究

Perturbation Method in Electromagnetic Field Research

对于非规则的电磁场边值问题，难以求得精确解．本文对此用摄动法进行近似分析．通过正则变换、摄动展开及假定边界面的近似表达式，使问题得到简化，进而得到满意的近似解．

It is very hard to gain an exact solution of irregular boundary-value problem of electromagnetic field. In this paper the perturbation method is applied to rational approximation for this. The complex problem becomes a simple one by regular transformation, perturbation series expansion and assumed approximate equation of boundary surface. And then we gain a satisfactory approximate solution. In expressing the solution we may study the influence of physical parameters upon electromagnetic field.
