| 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. |
