分析导体电磁场时有效磁导率和复磁导率的计算

Calculation of Effective Permeability and Complex Permeability Electro-magnetic Field in Ferro-magnetic Material

在计算铁磁媒质中非线性正弦电磁场时,需要对磁化曲线或磁滞回线进行处理。本文介绍了现有的几种处理方法,着重讨论时变电磁场数值计算中有效磁导率和复磁导率的计算方法,并论述了二者间的关系。

In calculating nonlinear electro-magnetic fleld,it is necessary to deal with the magnetization curve and hysteresis loop.In the paper,the calculating methods of effective permeability and corn plex permeability in numerical calculation of time varying electro-magnetic field,and the relation ship between the two methods are discussed.
