摘要:在分析及修正电流密度定义的基础上,讨论了电导率有限的导电媒质分界面上自由电流的存在情况,并给出了电导率为有限值的导电媒质分界面两侧电磁场的边界条件,从而澄清了教学科研与实际工程应用中的模糊认识.

关键词: 电导率, 电流密度, 边界条件

Abstract: Based on the analysis and modification of the definition of electronic current density,the question about the free current on the medium interface with limited conductivity is discussed.Further,the EM boundary conditions of medium interface with limited conductivity are given.It is available to clarify some mistiness for teaching in electromagnetics and the application in fact project.

Key words: conductivity, electronic current density, boundary condition
